摘要:
A panel unit is formed by sandwiching a liquid crystal display panel and a diffusion sheet between a front surface plate having a curved plane and a back surface plate having a curved plane. A light source unit is arranged on a back surface of the panel unit. The diffusion sheet is formed into an outward convex shape in the same manner as the liquid crystal display panel and hence, due to a lens action of the diffusion sheet, light from the light source unit is collected in the direction toward the center of a screen. Accordingly, it is possible to suppress a phenomenon that brightness in a periphery of the screen is reduced when the screen is viewed from a front side.
