发明名称 Liquid-crystal display device
摘要 One of the objects of the present invention is to provide a liquid crystal display device with high transmittance or viewing angle characteristics. A liquid crystal display device of the present invention includes: a first substrate (10) which includes a pixel electrode (30); a second substrate (20) which includes a counter electrode (25); and a liquid crystal layer (21) and a spacer (40) which are provided between the first substrate (10) and the second substrate (20). The pixel electrode (30) includes a first portion which is formed by a plurality of first branch portions (34A) extending in a first direction, a second portion which is formed by a plurality of second branch portions (34B) extending in a second direction, a third portion which is formed by a plurality of third branch portions (34C) extending in a third direction, and a fourth portion which is formed by a plurality of fourth branch portions (34D) extending in a fourth direction. The spacer (40) is provided at a position in the pixel (50) which is surrounded by the first to fourth portions of the pixel electrode (30) when viewed from a direction perpendicular to a plane of the first substrate (10).
