摘要：An optical film is fixed to another member (for example, fixed to anothermember), and even if a temperature change occurs when the dimensional change is notpossible due to a temperature change, the optical film has a reaction force against a

residual stress in the film plane. Reduce phase difference unevenness. A ratio of

dimensional change before and after heat treatment of a film in a first direction in whichshrinkage is maximum in the film plane when heat treatment is performed is T1 (%), andin the film direction in the first direction. When the dimensional change rate before andafter heat treatment of the film in the vertical second direction is T2 (%), and the heattreatment is a treatment that is allowed to stand for 24 hours at 100 ° C. and a relativehumidity of 0%, the optical film F is: The following conditional expressions (1) T1 <−0.2%,(2) T2 ≧ 0.05%, (3) −0.4% ≦ T1 + T2 <0.0% are satisfied.
