<P>PROBLEM TO BE SOLVED: To provide a light diffusing sheet restraining the glare phenomenon of a screen while maintaining glare-proof property even when it is applied to a high-definition LCD, hardly showing double refraction and made excellent in adhesion and durability. <P>SOLUTION: In the light diffusing sheet which has a resin coating film layer at least on one surface of a transparent film and where a light diffusion layer having fine rugged shape is formed on the surface of the resin coating film layer, the transparent film is constituted by incorporating (A) thermoplastic resin having a substitutable and/or non-substitutable imido group on a side chain and (B) thermoplastic resin having a substitutable and/or non-substitutable phenyl group and nitrile group on a side chain, and the surface having the fine rugged shape satisfies an average ridge distance (Sm; Sm≤80μm), center line average surface roughness (Ra; Ra≤0.25μm) and ten-point average surface roughness (Rz; Rz≤9Ra). <P>COPYRIGHT: (C)2004,JPO |
