Abstract:
1. A lateral electric field liquid crystal display device comprising: a substrate; a planar electrode formed in a planar form on the substrate; strip electrodes formed in a strip form on the planar electrode via an insulating film; and a liquid crystal aligned substantially in parallel to the substrate, the liquid crystal display device controlling a display by rotating the liquid crystal within a plane substantially in parallel to the substrate by an electric field between the planar electrode and the strip electrodes, wherein: each pixel constituting the display is divided into a first region and a second region; an extending direction of a strip electrode of the first region and an extending direction of a strip electrode of the second region are orthogonal; an alignment azimuth of the liquid crystal of the first region and an alignment azimuth of the liquid crystal of the second region are orthogonal; and an angle formed between the extending direction of the strip electrode in the first region and the alignment azimuth of the liquid crystal and an angle formed between the extending direction of the strip electrode in the second region and the alignment azimuth of the liquid crystal are the same, wherein: the liquid crystal has the pretilt angle larger than 0 degrees; the first region includes a third region and a fourth region whose pretilt angles face opposite directions from each other; and the second region includes a fifth region and a sixth region whose pretilt angles face opposite directions from each other.
