  • Patent number: 9276052
    Abstract: A display device includes a plurality of light-emitting elements aligned on a TFT substrate in a formation of a matrix. The plurality of light-emitting elements each have a flat surface portion and including a light-emitting layer, an anode, and a cathode, an insulating layer formed on the TFT substrate and under the light emitting element, and a tilted metal surface provided on a peripheral area surrounding the flat surface portion of the light-emitting element and having a tilt angle with respect to the flat surface portion of the light-emitting element. The tilted metal surface is provided on a surface of a slope of a bank that is provided on the insulation layer, and a width of a cross-section of the bank becomes smaller as the cross section comes farther away from a surface of the TFT substrate. A counter substrate is placed on the TFT substrate.

  • Publication number: 20160025962
    Abstract: [PROBLEM] To provide a display device capable of improving the transmittance of light at an opening that passes light while maintaining high reflectivity in a reflective layer. [RESOLUTION MEANS] Use a metal film and an reflection increasing film to configure a reflective layer provided in an element substrate to effectively utilize light of a light source. Leave a silicon nitride film that is one portion of the reflection increasing film in the opening that passes the light of the light source while removing the metal film. At this time, the film thickness of the silicon nitride film in the reflection increasing film is ¼ the wavelength of incident light and, on the other hand, the film thickness of the silicon nitride film in the opening is ½ the wavelength of the incident light. The silicon nitride film that is one portion of the reflection increasing film and a passivation film provided in a top layer of an interlayer dielectric film are laminated in the opening to achieve this structure.

  • Publication number: 20150123150
    Abstract: When the plane shape of a bank edge, that is, the direction of a line segment connecting the centers of pixels adjacent to each other (the direction of the pixels) is orthogonal to the direction of a line segment formed by the bank edge, light leaks from the adjacent pixels. The shape of the luminous region of the pixel of a display device, that is, the edge shape of a bank opening is formed as follows. The direction of an approximately linear portion (a line segment) formed by a bank edge is not orthogonal to the direction of the most closely adjacent pixel (an acute angle or an obtuse angle is formed by the directions).

  • Publication number: 20150123885
    Abstract: When a previously existing technique is applied to a white OLED, such a structure is adopted that the peak wavelength of the intensity of interference is the emission peak wavelength corresponding to blue or less. However, in this case, the intensity of interference of the wavelength range corresponding to red is reduced to decrease the light emission intensity of red. A display device is configured in which a stacked film configuring a white light emitting element (an organic light-emitting diode element) is configured in such a manner that the peak wavelength of the intensity of interference is the peak wavelength of the light emission intensity corresponding to blue or less. The light emission intensity of the light emitting element corresponding to a red pixel is made greater than the light emission intensity of the light emitting elements corresponding to pixels for other colors.

  • Publication number: 20150035738
    Abstract: In a color display device, when using white (W) sub-pixels in addition to subpixels of red (R) and green (G) plus blue (B) without increasing a wiring line number, the per-color pixel number in a unit area decreases so that the image resolution is deteriorated. The area and number of subpixels are adjusted in accordance with the visual sensitivity or luminosity required. Practically, the area of red (R) and blue (B) subpixels which are relatively low in luminosity is set to be about two times greater than the area of green (G) and white (W) subpixels that are relatively high in luminosity while letting the number of green (G) and white (W) subpixels be twice the number of red (R) and blue (B) subpixels. A larger subpixel is configured from a plurality of unit subpixels. A smaller subpixel is formed of a one unit subpixel.
