摘要： Because light diffusing plates constituting backlight units have high moisture absorbency, light diffusing plates cause deformation such as warp, swell and flexure and adversely affect other members such as liquid crystal cells to cause defective images. A backlight unit that does not generate defective images due to such deformation of light diffusing plate is provided. This backlight unit is a backlight unit 1 comprising light sources 13, a light diffusing plate 14 comprising a synthetic resin and disposed on the light sources, and one or more kinds of optical members 15 and 16 for backlight unit disposed on the light diffusing plate, wherein both surfaces of the light diffusing plate 14 shall have an arithmetical mean deviation (Ra) of 0.1 μm or less according to JIS B0601:1994.
