ABSTRACT:
The invention provides a high-image-quality, wide-viewing-angle liquid crystal display device that can be manufactured at low cost, and to provide an electronic apparatus provided with such a liquid crystal display device. A liquid crystal display device of the invention can include an upper substrate and a lower substrate which are disposed facing each other, a liquid crystal layer interposed between the upper substrate and the lower substrate, an upper polarizer and a lower polarizer which are separated by the liquid crystal layer and are disposed adjacent to two opposite sides of the liquid crystal layer, and a liquid crystal panel having dot regions each provided with a transmissive display area and a reflective display area. One of the upper substrate and the lower substrate can be provided with a liquid-crystal-layer thickness adjustment layer on a side of the substrate adjacent to the liquid crystal layer. This liquid-crystal-layer thickness adjustment layer provides different thicknesses for the liquid crystal layer in the transmissive display area and the reflective display area. The upper substrate has a light-diffusing layer disposed adjacent to the outer surface of the upper substrate. A half-width α for the contrast-versus-viewing-angle characteristics of the liquid crystal panel and a half-width β for the diffusion characteristics of the light-diffusing layer satisfy the relationship α≧3β.
