Liquid crystal display device and electronic apparatus
View Patent ↗The invention can provide a liquid crystal display device in which a homeotropic alignment liquid crystal layer is interposed between a pair of substrates and a transmissive display region and a reflective display region are provided in one dotregion. A liquid crystal layer thickness-adjusting layer for making the thickness of the liquid crystal layer in the reflective display region smaller than the thickness of the liquid crystal layer in the transmissive display region can be formed between at least one substrate of the pair of substrates and the liquid crystal layer, and wherein, in at least one substrate of the pair of substrates, convex portions that protrude from the internal surface of the substrate to the inside of the liquid crystal layer are formed in the transmissive display region in the dot region and in the region where the liquid crystal layer thickness-adjusting layer is formed outside the dot region. Accordingly, the invention can provide a liquid crystal display device capable of displaying images with a wide angle in both of transmissive display and reflective display.
