摘要： There is provided a direct backlight type liquid crystal display device having high light diffusability, keeping excellent color and having high brightness. The direct backlight type liquid crystal display device is a direct backlight type liquid crystal display device comprising: a backlight source, a light diffusion sheet which may have a protective film on a surface thereof which faces the backlight source or both surfaces thereof as desired, a light ray adjusting film, and a liquid crystal panel, wherein the light diffusion sheet is formed from a composition comprising predetermined amounts of (C) at least one heat stabilizer (component C) selected from the group consisting of a phosphate compound (component C-1), a phosphate compound (component C-2) and a phosphonite compound (component C-3), (D) an ultraviolet absorber (component D) and (E) a fluorescent whitening agent (component E), based on 100 parts by weight of the total of (A) an aromatic polycarbonate resin (component A) and (B) polymeric fine particles (component B) having an average particle diameter of 0.01 to 50 μm.
