ABSTRACT:
A liquid crystal display device comprising a pair of substrates with liquid crystal layer therebetween, a plurality of gate signal lines and a plurality of drain signal lines formed on one of the pair of substrates, at least a pixel electrode and a plurality of counter electrodes formed on the one of the pair of substrates in each pixels, at least one of the plurality of counter electrodes extend along a drain signal line overlapping to the drain signal lines with at least one of an insulation film therebetween, and the drain signal line has two or more regions which differ in distance between a surface of the drain signal line and the counter electrode.
