ABSTRACT:
Electric field adjusting layers each of which is different from an aligning film in at least one of a resistivity and a dielectric constant are formed in each pixel on a pixel electrode of a first substrate. An electric field applied to a liquid crystal partially changes in each pixel, and regions which are different from each other in aligned state are formed in each pixel. Therefore, a field angle is widened. A value .DELTA.n.d of the liquid crystal is preferably set to be 600 nm or more.
