Abstract: A liquid crystal display device (1) of the present invention includes a display panel (3) and a backlight (2) (an illumination device). The backlight (2) includes a light-emitting layer (20) in which a plurality of light sources (5) are scattered and a diffuser (7) (a diffusion layer) that is formed on the light-emitting layer and diffuses light from the light-emitting layer. The light sources (5) that are present within the light-emitting layer (20) emit light in a direction (a direction of an arrow) substantially parallel to a boundary surface between the light-emitting layer (20) and the diffuser (7). In the diffuser (7), a transmittance of light in an area (7c) close to each of the light sources is smaller than a transmittance of light in an area that is far from each of the light sources.

Abstract: One embodiment of the present invention discloses a liquid crystal display device, and more particularly a transmissive-type liquid crystal display device including a backlight on a back of a panel. The liquid crystal display device includes a gray scale signal generating portion including an input image luminance level analyzing circuit that obtains luminance level distributions of respective colors based on RGB image signals, a correction coefficient calculating circuit that calculates correction coefficients based on the luminance level distributions of the respective colors, and an image signal correcting circuit that corrects luminance levels indicated by the RGB image signals, based on the correction coefficients; and an amount-of-backlight-light control circuit that adjusts amounts of lights emitted from LEDs for the respective colors based on the correction coefficients. In the correction coefficient calculating circuit, correction coefficients are calculated such that a difference in luminance level distribution between the RGB colors is reduced by corrections to luminance levels. In the amount-of-backlight-light control circuit, the amounts of lights emitted for the respective colors are adjusted such that changes in luminance levels and changes in the amounts of lights emitted are mutually cancelled out.
