20090128750LIQUID CRYSTAL DISPLAY AND THIN FILM TRANSISTOR SUBSTRATE THEREFOR - The invention is directed to an improved flat panel liquid crystal display (LCD). In one embodiment the improved LCD includes a liquid crystal layer that completely fills a gap formed between a color filter array and a thin film transistor (TFT) array. The TFT array includes a substrate that includes one or more pixel areas. Each pixel area may be divided into at least two pixel sub-areas. Each pixel sub-area is configured to have a different electric field than its counterparts, such that mutual compensation in the sub-areas decreases distortion of a gamma curve and improves lateral visibility of the flat panel display. In one embodiment, a first pixel electrode is formed in a first of the at least two pixel sub-areas; and a second pixel electrode is formed in a second of the at least two pixel sub-areas.05-21-2009
