Patent ID: 7456924

Claim:
A liquid crystal display device comprising: first and second substrates with a liquid crystal layer therebetween; a plurality of gate signal lines made of metal and a plurality of drain signal lines made of metal, the gate signal line and the drain signal line have a first overlapping region; a plurality of counter voltage signal lines, the counter voltage signal line and the drain signal line have a second overlapping region; a plurality of pixel regions defined by neighboring gate signal lines and drain signal lines; and a pixel electrode and a counter electrode formed on the first substrate in each pixel region; wherein the pixel electrode has a plurality of slits, the counter electrode has a substantially rectangular shape without a slit, and the pixel electrode is arranged in a position which overlaps with the counter electrode; wherein a thin film transistor having a semiconductor layer is formed on the gate signal line; and wherein the semiconductor layer at least overlaps with the drain signal line at the first overlapping region and the second overlapping region.
