Abstract

There is provided a liquid crystal display device comprising a liquid crystal layer, which includes a liquid crystal having a negative dielectric anisotropy exhibiting vertical alignment as an initial alignment state, between a pair of substrates and disposed to be opposite to each other, in which alignment control means for controlling alignment of the liquid crystal layer is provided on at least one of electrodes provided on the pair of substrates, and in which a light-shielding film BM two-dimensionally overlapped with the alignment control means is provided on at least one substrate of the pair of substrates.

Description

technical field [0001] The present invention relates to a liquid crystal display device and electronic equipment. Background technique [0002] Currently, a TN twisted nematic (Twisted Nematic) mode of a normally white mode is known as the most widely used mode in liquid crystal display devices. Recently, as liquid crystal display devices have been greatly improved, their image quality has also risen to the same level as that of CRTs. However, the TN mode liquid crystal display device has a disadvantage of a narrow viewing angle. To solve this problem, the VA (Vertical Alignment) mode in which liquid crystals with negative dielectric anisotropy are vertically aligned between a pair of opposing substrates has emerged, and LCD TVs and the like have been commercialized. The VA mode liquid crystal display device has the characteristics of wide viewing angle and high contrast ratio. [0003] In addition, it is known that a VA mode liquid crystal display device employs a struct...
