摘要:
A liquid crystal display device having a plurality of pixels arranged in the form of a matrix and means for applying voltage signals to change the light transmission factor or light reflection factor of said pixels, said liquid crystal display device comprising:
a liquid crystal layer made of twistable liquid crystal molecules (LC),
a first substrate (SUB1) and a second substrate (SUB2) sandwiching said liquid crystal layer therebetween at least one of which is transparent;
at least one polarizing means (POL1, POL2),
at least a pair of a pixel electrode (PX) and a counter electrode (CT) formed in each of said pixels between the surface of said first substrate (SUB1) and the surface of said liquid crystal layer in order to control the twisting amounts of liquid crystal molecules of said liquid crystal layer by use of an electric field which is established between said pixel electrode (PX) and said counter electrode (CT) and has a component (EDR) in parallel with said first substrate (SUB1), and
a video signal line (a), a signal electrode (GT) and a switching element (TFT) provided in each of said pixels between said first substrate (SUB1) and said liquid crystal layer to feed video signals to said pixel electrode (PX) through said video signal line (DL), said signal electrode (GT) and said switching element (TFT);
wherein said counter electrodes (CT) of adjacent pixels are positioned on both sides of said video signal line (DL), and the widths of said counter electrodes (CT) in the lateral direction are not smaller than one-half the width of said video signal line (DL).
