Abstract:
An optical film of the present invention includes a positive A-plate and a positive C-plate, in which the Re(450), Re(550), and Re(650) of the positive A-plate satisfy the relationship of Re(450)≦Re(550)≦Re(650), the positive A-plate is formed of a cured product of a composition including the liquid crystal compound A, and the positive C-plate is formed of a cured product of a composition including the liquid crystal compound C.
