Abstract
Provided is a viewing angle control polarizing plate that has asymmetric transmission characteristics, does not cause moire even in a case of being used in combination with a high-definition image display device, and is capable of easily following a curved surface and a viewing angle control system with high productivity. The viewing angle control system includes at least a first polarizer and an optically anisotropic layer, in which an absorption axis of the first polarizer forms an angle of 45° or greater with respect to an in-plane direction, and a main axis of a refractive index of the optically anisotropic layer is tilted in the in-plane direction.
