Patent ID: 7245433

Claim:
A light-diffusing sheet comprising 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 a transparent film, wherein 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, wherein a ratio of an internal haze value to a total haze value of the light-diffusing sheet (internal haze value/total haze value) is 0.5 or more and less than 1 and the total haze value is in the range of from 30% to 70%, wherein the total haze value is a haze value of a light-diffusing sheet and the internal haze value is a value obtained by subtracting a haze value 11% from a haze value measured in a state where a pressure-sensitive adhesive coated transparent sheet having a haze value 11% is adhered onto the minute of unevenness shape surface rough of the light-diffusing sheet.
