Abstract: Dissipation of heat generated by a luminescent source, such as a fluorescent lamp, of a backlight apparatus and an LCD therewith is enhanced by providing a proximity section in a holder, making the hottest part the closest to the holder for efficient heat conduction.

Abstract: A display apparatus comprises a display element, a backlight apparatus provided behind the display element and having a metal case, and a housing accommodating the display element and the backlight apparatus. In the display apparatus, electric wires for providing power to the backlight apparatus extend between the metal case of the backlight apparatus and the housing, and at least one opening is provided in the metal case in a part where the electric wires extend.

Abstract: A liquid crystal display device includes first and second frame members, between which a light source device, a metal body supporting the light source device, a frame-like cover covering the peripheral region of the light source device, and a liquid crystal display element are held by the cover. The first frame member covers the peripheral region of the liquid crystal display element and has hooks for engagement with the recess in metal body. Therefore, the metal body, the light source device, the cover, the liquid crystal display element, and the first frame member are assembled and fastened together by the engagement of the hooks with the metal body. This assembly can be coupled to the second frame member. Straight metal members can be arranged between the first frame member and the driving ICs on the liquid crystal display element.

Abstract: A liquid crystal display unit having a liquid crystal display element is accommodated in a housing having an opening for exposing the display portion of the display element to the exterior. The housing comprises a display face cover and a rear cover and the liquid crystal display unit is mounted directly relative to the display face cover. A positioning pin is provided so as to extend out from the display face cover in order to position the liquid crystal display unit relative to the display face cover, and a positioning hole, which engages the positioning pin, is provided on the liquid crystal unit.

Abstract: A liquid crystal display apparatus includes a liquid crystal panel having front and rear surfaces, a printed circuit board for driving the liquid crystal panel, and an optical waveguide for illuminating the front surface of the liquid crystal panel, the optical waveguide including first and second planes, and a thick side and a thin side, wherein the second plane is inclined with respect to the first plane, wherein the liquid crystal panel is inclined with respect to the first plane of the optical waveguide, wherein the second plane of the optical waveguide faces the liquid crystal panel, wherein a space portion having a size based on the difference between the thickness of the thick side and the thin side is situated at the thin side of the optical waveguide, and wherein at least a portion of the printed circuit board is disposed in the space portion.

Abstract: Polarity patterns (polarity pattern signal POL) are stored in a ROM in a polarity pattern controlling portion. Then, the polarity pattern is changed according to applications of a liquid crystal display panel. Since the polarity pattern is stored in the ROM, the polarity pattern can be changed without modification of a hardware. Also, two sets of polarity patterns or more are stored in the ROM, and then any one polarity pattern can be output according to the application. In addition, the polarity pattern signal POL and image signals RGB are compared with each other, and then the polarity pattern which is to be read from the ROM is switched according to the result.

Abstract: The present invention relates to a light source device including discharge tubes that emit light by discharging in a thin atmosphere, a method of producing the light source device, and a display apparatus in which the light source device is employed. This light source device includes discharge tubes and a heat conductive member that is brought into contact with the neighboring area of the electrodes of the discharge tubes so as to locally cool down the neighboring area of the electrodes. In the light source device, a low heat conductivity member having lower heat conductivity than the heat conductive member is interposed between the heat conductive member and the discharge tubes. With such a structure, the luminance in the entire light source device can be increased and made uniform, and the reliability of the light source device can be increased accordingly.
