ABSTRACT:
A liquid crystal display device includes 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, wherein the gate signal line and the drain signal line have a first overlapping region, and a plurality of counter voltage signal lines, wherein the counter voltage signal line and the drain signal line have a second overlapping region. A plurality of pixel regions are defined by neighboring gate signal lines and drain signal lines, and a pixel electrode is formed on the first substrate in each pixel region. A thin film transistor having a semiconductor layer is formed on the gate signal line, and the semiconductor layer at least overlaps with the drain signal line at the first overlapping region and the second overlapping region.
