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, a video signal line formed on a face of the first substrate. At least one pixel electrode is fed with a video signal through the video signal line, and at least one counter electrode fed with a counter voltage, the pixel electrode and the counter electrode being opposed to each other. The twisting extent of the liquid crystal moles is controlled by an electric field component which is generated between the pixel electrode and the counter electrode. A spacing between the pixel electrode and the counter electrode arranged to oppose each other is larger than a width of at least one of the pixel electrode and the counter electrode and smaller than a spacing between the pixel electrode and the video signal line.
