<P>PROBLEM TO BE SOLVED: To provide a light diffusive sheet having excellent adhesion and durability by maintaining glare shielding, hardly recognizing white blur due to surface dispersion and hardly displaying birefringence. <P>SOLUTION: The light diffusive sheet forms a resin membrane layer forming fine irregular shapes on at least one side of a transparent film, and a light diffusive layer having a lower refractive index than that of the resin membrane layer on a fine irregular shape surface of the resin membrane layer. The transparent film contains (A) a thermoplastic resin having substituted and/or unsubstituted imide group on a side chain, and (B) a thermoplastic resin having substituted and/or unsubstituted phenyl group and nitril group. The low refractive index layer is formed of a material having a polysiloxane structure. Glosiness at 60° of a low refractive index layer surface provided on the surface of the resin membrane layer is 15% or more and 50% or less in the state that the resin membrane layer and the low refractive index layer are formed. <P>COPYRIGHT: (C)2004,JPO |
