Abstract: A display device includes a display panel unit and a backlight unit which radiates light toward the display panel. The display panel unit includes a display panel on an upper surface of a box-shaped panel housing which has first projecting portions on side walls of the housing. The backlight unit incorporates a light source in a bottom portion of a box-shaped light source housing which has second projecting portions on side walls of the light source housing. By bringing the first projecting portions and second projecting portions into contact with each other, a distance between the light source of the backlight unit and the display panel can be held. Further, by forming third projecting portions which project further than the first projecting portions on the panel housing, handling of the display panel unit is facilitated.

Abstract: A liquid crystal display device is provided, where dust can be prevented from entering into the display device and the quality of the display can be prevented from lowering even in the case where a fan in the main body of the equipment blows air against the rear surface of the display device. The display device having a liquid crystal panel and a backlight illuminating the liquid crystal panel that are integrated with an upper frame that covers a periphery of the front surface of the liquid crystal panel and sides of the backlight is characterized in that a cable for supplying power to a light source provided inside the backlight is led out between a side of the backlight (side mold) and the upper frame, and a portion through which the cable is led out is covered by a sheet.

Abstract: Plural light-emitting diodes are disposed in an on-line arrangement on a surface a circuit board facing an optical guide and spacers having a projecting dimension larger than the projecting dimension of this light-emitting diode from the surface are disposed adjacent to the light-emitting diode on the surface of the circuit board.

Abstract: A frame area of a liquid crystal display device is reduced by improving the layouts of extraction lines DTM of drain wiring of a TFT liquid crystal display device, a driving IC of the TFT liquid crystal display device and a flexible board FPC2 for a drain driving circuit of the TFT liquid crystal display device.

Abstract: A liquid crystal display device includes a liquid crystal display element having a liquid crystal layer sandwiched between a pair of upper and lower substrates, a flexible circuit board disposed around a periphery of the liquid crystal display element, an illuminating light source having a line light source, a light guide and a reflector and disposed behind the liquid crystal display element, a metal upper case having a sidewall bent back and a display window, a resin lower case for housing the illuminating light source. The upper and lower cases are clamped by crimping plural nails formed in the sidewall of the upper case at an outer surface of the lower case after stacking the liquid crystal display element, the flexible circuit board and the illuminating light source between the upper and lower cases.

Abstract: Herein disclosed are a liquid crystal display device and a data processing device, which can have their frame portions reduced in area to reduce the size and weight by extracting the terminals of video signals to only one side of a liquid crystal display panel and by arranging a video signal line driving circuit substrate to be connected with the terminals, only at one side of the display panel.

Abstract: A liquid crystal display device in which a back light is arranged below a liquid crystal display panel having a plurality of pixels arrayed on a transparent substrate surface and in which a prism plate having a plurality of stripe grooves arrayed in parallel is arranged between the liquid crystal display panel and the back light. If the stripe grooves has a pitch .lambda..sub.1 (mm) and if the pixels in parallel with the stripe grooves has a pitch .lambda..sub.2 (mm), the liquid crystal display device is constructed to satisfy a relation of .lambda..sub.1 .ltoreq.0.075.lambda..sub.2 /(.lambda..sub.2 +0.075). This construction can increase the brightness of the back light and prevent the interference fringes from being formed on the display frame.
