摘要 The present invention, a light diffusing sheet comprising a transparent resin layer having a minute unevenness formed on a surface thereof on at least one side of a transparent substrate, and a haze value of the light diffusing sheet is 30% or more, a ratio (Ra/Sm) of a center-line average surface roughness (Ra: mum) and an average height-depth spacing (Sm: mum) is 0.005 or less, and the Ra satisfies a relationship of 0.1<=Ra<=0.4. The light diffusing sheet enables suppression of glaring of a screen and white blurring, while maintaining antiglare property, having excellent image visibility.
