Abstract
(EN)
A circularly polarizing plate (1) according to the present invention comprises: a λ/4 layer (40); and a polarizing layer (41) which is superposed on the λ/4 layer (40) and contains a lyotropic liquid crystal. With respect to this circularly polarizing plate (1), an overcoat layer (42) is formed so as to cover the upper surface and the lateral surface of the polarizing layer (41) and the lateral surface of the λ/4 layer (40).
