Abstract
Pixel electrodes adjacent to each other along a first axis are supplied with pixel potentials having opposite polarities with respect to a potential of a common electrode. The pixel electrode includes straight parts. Electric fields between the straight parts and the common electrode are applied to negative type liquid crystal material. An electric field between the straight parts of the adjacent pixel electrodes is applied to the negative type liquid crystal material. An opposite substrate includes a second region opposed to a first region between the straight parts of the adjacent pixel electrodes. At least a part of visible light transmitted through the first region is transmitted through the second region. Angles of the straight parts with respect to an axis perpendicular to direction of initial alignment of the liquid crystal material have a size of not less than 15° and not more than 30°.
