PROBLEM TO BE SOLVED: To obtain a light diffusion plate, optical element, and liquid crystal display device which has superior preventablilty against glares and dizziness performance, while maintaining a preventing function against ghost. SOLUTION: This light diffusion layer has on one surface a fine uneven structure 11, having a surface roughness such that a 60 deg. mirror surface luster is 10 to 70%, the center line mean roughness is 0.1 to 0.35 μm, and a mean top to bottom interval is 18 to 60 μm, the optical element has a light diffusion layer 1 on one or both the surfaces of an optical layer, and the liquid crystal display device has a light diffusion layer on the viewing side of a liquid crystal display element. |
