Abstract:
A liquid crystal display device comprising:a liquid crystal display panel having a pair of substrates being superposed one on another, a liquid crystal layer sealed therebetween, drive elements or tape carrier packages being mounted on an end of the one of the pair of substrates so as to be juxtaposed with each other along the end of one of the pair of substrates; an optical guide plate being disposed along one of surface sides of the liquid crystal display panel; a linear shaped light source being disposed at one side of the optical guide plate; an optical diffusing sheet being disposed between the one of surface sides of the liquid crystal display panel and the optical guide plate; an optical reflecting sheet being disposed at an opposite side of the optical guide plate to the one of surface sides of the liquid crystal display panel; and a pattern for preventing brightness irregularity from appearing in a display screen area of the liquid crystal display panel, which has a plurality of regions being formed on at least one edge of at least one of the optical guide plate, the optical diffusing sheet, and the optical reflecting sheet and being juxtaposed along the at least one edge thereof, and each of the plurality of regions is extended towards the display screen area and confronts an area lying between a pair of the drive elements of the tape carrier packages.
