Abstract
A liquid crystal display device having first and second substrates with a liquid crystal layer therebetween, a plurality of gate signal lines and a plurality of drain signal lines, a plurality of counter voltage signal lines, a plurality of pixel regions defined by neighboring gate signal lines and drain signal lines and a counter electrode and a pixel electrode being formed on the first substrate in each pixel region and enabling forming of an electric field therebetween. The counter electrode is of planar shape and, the pixel electrode is of planar shape with plurality of slits and is overlapped with the counter electrode with an insulating layer provided therebetween. Both the counter electrode and pixel electrode are made of a transparent conductor. The counter voltage signal line is made of metal and extends in center region in each pixel region and is directly connected to the counter electrode.
