摘要:
An optical film includes: a layer A formed of a resin composition P1 containing a resin x1 having a positive intrinsic birefringence value and a resin y1 having a negative intrinsic birefringence value; and a layer B formed of a resin composition P2 containing a resin x2 having a positive intrinsic birefringence value and a resin y2 having a negative intrinsic birefringence value. In the optical film, retardations R450, R550, and R650 at an incident angle of 0° satisfy the relationship of R450
