Abstract: The invention relates to a light source device utilizing an array of discrete light sources and a display having the same and provides a small and thin light source device capable of achieving high display quality and a display having the same. A planar light guide plate is employed which has point light sources that emit light, a first light-emitting region provided in an area other than the neighborhood of one of the point light sources and having a first lighting element for taking out light guided from the side of the point light source, and a second light-emitting region provided in an area other than the neighborhood of the other point light source and having a second lighting element for taking out light guided from the side of the point light source.

Abstract: The invention relates to a substrate for a liquid crystal display used in a display section of an information apparatus and a liquid crystal display having the same and provides a substrate for a liquid crystal display and a liquid crystal display having the same that provide good display characteristics without any increase in manufacturing steps. A configuration is employed which includes a plurality of gate bus lines formed on a substrate substantially in parallel with each other, a plurality of drain bus lines formed on the substrate such that they intersect the gate bus lines with an insulation film interposed therebetween, pixel regions provided on the substrate in the form of a matrix, pixel electrodes having a plurality of electrode units formed in the pixel regions, slits formed between the electrode units, and connection electrodes for connecting the plurality of electrode units with each other and a thin film transistor formed at each pixel region.

Abstract: A liquid-crystal-display device which displays an image on display matrix by supplying video signals to pixel cells of the display matrix includes a data driver supplying the video signals to the display matrix and including N digital drivers, N×k common-signal lines, and N×k×n switch blocks, wherein every k lines of the N×k common-signal lines are connected to a corresponding one of the N digital drivers, and every n blocks of the N×k×n switch blocks are connected to a corresponding one of the N×k common-signal lines, each of the common-signal lines being comprised of m lines and each of the switch blocks includes m selection switches, which couples the common-signal lines to the pixel cells of the display matrix.

Abstract: A display device used for a display unit of portable electronic equipment, a light source device therefor and a light guide plate, suppressing dispersion in the brightness and featuring a high contrast and a good display quality. The constitution includes a light incidence surface on where light emitted from an LED falls, a light reflection surface formed facing the light incidence surface and reflects light from the light incidence surface, a light outgoing surface arranged between the light incidence surface and the light reflection surface, and has a circularly polarizing plate intimately adhered onto the surface thereof, and an opposing surface formed facing the light outgoing surface and in which there are alternately arranged first opposing surfaces for guiding the incident light to the light outgoing surface as well as to the light reflection surface, and second opposing surfaces for emitting the light reflected by the light reflection surface through the light outgoing surface.
