First Claim
Patent Images
1. An illumination device capable of adjusting luminance per light-emitting region, comprising:
- first partition walls by which a plurality of light-emitting regions are separated;
light sources each for emitting light having different wavelengths, the light sources being provided in a respective of the plurality of light-emitting regions;
second partition walls which are provided higher than the first partition walls and which enclose the plurality of light-emitting regions;
optical means for diffusing the light emitted from each of the light sources, the optical means being supported by the second partition walls; and
a diffusion section for diffusing the light emitted from the each of the light sources, the diffusion section being fixed on the first partition walls so as to be disposed on upper sides of the plurality of light-emitting regions.

Abstract
An illumination device 10 includes a diffusion plate 13 for diffusing light emitted from light sources 17, which diffusion plate 13 is fixed on first partition walls 11 and provided on upper sides of light source blocks 18. The arrangement makes it possible to provide a high-quality illumination device and a high-quality liquid crystal display device in each of which unevenness in luminance and color is restrained so that a luminance distribution becomes constant.
