Patent ID: 8054441

Claim:
A laminated optical film comprising: a first optical anisotropic layer, and a second optical anisotropic layer, wherein Relationship (1) is satisfied when a slow phase axis of the first optical anisotropic layer is substantially perpendicular to a slow phase axis of the second optical anisotropic layer, −10 nmΔ Re 1 −ΔRe 2≦10 nm Relationship (1) wherein Relationship (2) is satisfied when the slow phase axis of the first optical anisotropic layer is substantially parallel to the slow phase axis of the second optical anisotropic layer, and −10 nm≦ Re 1 +ΔRe 2≦10 nm Relationship (2) wherein an in-plane retardation value Re of the laminated optical film as a whole satisfies 30 nm≦Re≦500 nm, where ΔRe1 denotes a value obtained by calculating the expression Re1 (at a temperature of 50° C.)−Re1 (at a temperature of 25° C.) concerning the first optical anisotropic layer, and ΔRe2 denotes a value obtained by calculating the expression Re2 (at a temperature of 50° C.)−Re2 (at a temperature of 25° C.) concerning the second optical anisotropic layer.
