    摘要: A light-diffusing sheet of the present invention comprises a transparent film and a light-diffusing layer, which is made of a resin coating layer having a minute unevenness formed on a surface thereof, is formed on at least one side of the transparent film. The transparent film includes a thermoplastic resin (A) having a substituted and/or non-substituted imido group in a side chain, and a thermoplastic resin (B) having a substituted and/or non-substituted phenyl group and nitrile group in a side chain, and the surface with the minute unevenness satisfies an average height-depth spacing (Sm): Sm≦80 μm, a center-line average surface roughness (Ra): Ra≦0.25 μm and a ten-point average surface roughness (Rz): Rz≦9Ra. The light-diffusing sheet, even in a case of application to a high definition LCD, is suppressing a screen glittering phenomenon while maintaining antiglareness, exhibiting almost no birefringence, and excellent in adhesion and durability.
