    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:μm) and an average height-depth spacing (Sm:μm) 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.

    摘要: The antiglare layer includes at least one resin coat layer (a) containing particles and a resin coat layer (b) laminated on said resin coat layer (a). The resincoat layer (b) contains particles and has a surface uneven configuration. An average particle size of the particles contained in the resin coat layer (b) is smaller than or equal to an average particle size of the particles contained in the resin coat layer (a), is capable of restraining the screen glaring phenomenon while maintaining the antiglare property and in which the whiting is observed to the least extent.
