Abstract

In a liquid crystal display device including a pair of substrates which face each other with a liquid crystal layer disposed therebetween, a plurality of pixel regions which are formed on one substrate, a planar counter electrode which is formed on each pixel region, and a comb-shaped or slit-shaped pixel electrode which is formed on each pixel region, the comb-shaped or slit-shaped pixel electrode being formed over the counter electrode by way of an insulation layer, a notch or a slit is formed in the counter electrode such that a wiring layer made of an opaque material which transmits a potential to the pixel electrode from a thin film transistor defines a region where the wiring layer is not overlapped relative to the counter electrode.
