Abstract
A liquid crystal display device including a liquid crystal composition layer having twistable liquid crystal molecules, a first substrate and a second substrate having the liquid crystal composition layer disposed therebetween, and a video signal line formed between a face of the first substrate and a face of the liquid crystal composition layer with at least one pixel electrode and at least one counter electrode being formed at each of pixels adjoining each other across the video signal line. The pixel electrode is fed with a selected video signal through the video signal line, and the counter electrode is fed with a counter voltage. The twisting extent of the liquid crystal molecules is controlled by an electric field which is generated between the pixel electrode and the counter electrode and which has a component substantially parallel to said first substrate. One of the counter electrodes of the individual pixels is positioned at opposite sides of the video signal line, and the one of the counter electrodes has a width which is at least equal to one half of the width of the video signal line.
