ABSTRACT:
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 in to 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.
