Abstract: A fluorescent luminous tube is provided that has a getter mirror film formed in an arbitrary shape by illuminating a laser beam onto a getter. In order to form the getter film 32, the rectangular ring-less getter 31 mounted on the anode substrate 11 is irradiated with the laser beam L from the outside of the front substrate 12 and thus is evaporated. In this process, when the illumination spot of the laser beam L is moved along the scanning line 33, the rectangular getter mirror film 32 is formed around the scanning line 33. The burnt region 34, which has the same shape and size as those of the scanning line 33, is formed using the laser beam L.

Abstract: An electrodeless discharge lamp includes an induction coil that includes a core and a winding wound around the core and generates an electromagnetic filed inside a bulb, an insert portion provided inside the core, and a plane portion that releases heat from the insert portion to the outside of a case. A tolerance in the inductance of the induction coil is reduced by spacing the end portion of the core on the side of the plane portion apart from the plane portion, which makes reliable start-up possible.

Abstract: An organic EL display in which the film thickness of an organic emissive layer is made uniform so as to increase the effective light emission area. An anode and a common cathode are formed for each pixel on the organic EL display. Switching by thin-film transistors causes current to flow between the anode and the cathode so that the organic EL element emits light. The organic EL element comprises a hole transport layer, the organic emissive layer, and an electron transport layer. Among a plurality of pixels disposed in a matrix configuration, the organic emissive layer is formed in common with adjacent pixels of the same color. Forming the organic emissive layer in common can prevent a decrease in the film thickness of the organic emissive layer at the edges of the shadow mask during vapor deposition and result in a uniform film thickness of the organic emissive layer.

A red filter, a green filter, and a blue filter are formed on a substrate for sealing by printing so as to face the organic EL devices. By overlapping at least two filters out of the red, green, and blue filters by printing, a black matrix is formed so as to face the boundary region of the organic EL devices, so that external light reflection by a wiring electrode between the devices is suppressed.

Abstract: An image-forming apparatus includes a first substrate, a second substrate, and a spacer that defines the spacing between the first substrate and the second substrate. The spacer has a portion ruggedized with grooves on the surface thereof exposed in the space between the first substrate and the second substrate. The grooves extend in a striped fashion substantially parallel with the first substrate and the second substrate. The ruggedized portion includes a plurality of regions, which are different from each other, in the ruggedized configuration. The image-forming apparatus thus controls an electron beam with a high accuracy, with no disturbance caused by the spacer.

The organic light-emitting device is press-fit in vacuum using a wrapping film (105) that is covered with a DLC film (or a silicon nitride film, an AlN film, a film of a compound expressed as AlNXOY) (106) containing Ar. The organic light-emitting device thus can be completely shut off from the outside, and moisture, oxygen, or other external substances that accelerate degradation of an organic light emitting layer can be prevented from entering the organic light-emitting device.

Abstract: A cold cathode discharge device with high efficiency of light emission and long life is prepared by a cold cathode having both high secondary electron emission and anti-spattering property. Using carbon system cold cathodes constituted of a mixed phase of diamond and graphite, a cold cathode discharge device with high efficiency of light emission and long life is realized. It is desirable that an element having a wavelength of light emission equal to or shorter than 200 nanometers should be mixed in the discharge gas.

Abstract: A shaped light extraction luminaire to gather light from an organic light emitting diode (OLED). Specifically, an inverted and truncated pyramid structure having a recessed area configured to receive an OLED is provided. The luminaire is structured to increase the light emission of the OLED by capturing light emissions that would typically be lost by absorption within the OLED. The luminaire includes angled sides having a reflective material disposed thereon. The luminaire increases the light output of the OLED such that it may be implemented in area lighting applications. Further, an array comprising a plurality of recessed areas and a plurality of angled sides for each of the recessed areas may be implemented.

Abstract: A glass member for use in a cathode ray tube is provided, which can facilitate the heating and softening of glass during sealing and raise the productivity without decreasing the mechanical strength of the product by improving the shapes of the seal end faces of the panel and funnel. In an edge area between an edge of the seal end face of each side part of the glass member for use in the cathode ray tube comprising a glass panel or a funnel and a position about 5 mm away along a tube axis from the edge, a thin edge part is formed to have a thickness decreasing part. The rate of thickness decreasing thereof toward the edge is larger than that of a standard shape in a root area adjacent to the edge area. Also, the thin edge part is formed so that an inequality of 0.3?t1/t0?0.7 is satisfied where t1 is a thickness at a position 1 mm away along the tube axis from the edge, and t0 is a thickness at a position 5 mm away along the tube axis from the edge.

As an end, the resolution, focusing quality and brightness of the screen of the monochromic CRT are improved.

Abstract: An oxide composite particle of the present invention is composed of at least one fine gold particle contained in a matrix of an oxide particle or at least one fine gold particle supported fixedly on the surface of an oxide particle, and absorbs a visible light having a specific wavelength. A phosphor of the invention has a thin film which is composed of such oxide composite particles on the surface of a phosphor particle of red or the like.

Further, in a color filter of the invention, a filter layer of at least one color formed on an inner surface of a panel is a thin film composed of the above-described oxide composite particles.

Abstract: An object is to improve the element characteristic of a luminescent element. In an anode 122 connected to a drain interconnection 120 of a current-controlling TFT 202, slits are made. A transparent hole generating layer 124 is formed on the anode 122. Since the slits are made, luminescence can be taken out even if a light-shielding metal film is used as the anode 122. Since the hole generating layer 124 has semiconductivity, an electric field applied from the anode 122 to an organic compound layer 125 can be made uniform. Since holes are generated in the hole generating layer 124, the density of carriers injected from the anode 122 can be made high. In this way, a luminescent element having a low driving voltage and a high brightness can be manufactured.

Abstract: Disclosed are an organic EL(electroluminescence) display panel and a fabrication method thereof. The auxiliary electrode is formed to alternate but be overlapped with the pattern of the first electrode with a predetermined area so as to increase the pixel area as much as the overlapped area. Therefore, the present invention improves an opening ratio of the organic EL device. And, the present invention requires no additional step of forming an insulating layer for increasing an opening ratio, thereby saving a product cost for the fabrication of the organic EL device as well as being advantageous in fabrication efficiency.
