1. A viewing angle control system comprising:
a polarizer; and
a light absorption anisotropic layer,
wherein the direction of the absorption axis of the polarizer is parallel to the in-plane direction of the polarizer,
an angle θ between a transmittance central axis of the light absorption anisotropic layer and a normal line of the light absorption anisotropic layer is in a range of 0.1° to 45°, and
an angle φ between a direction in which the transmittance central axis of the light absorption anisotropic layer is orthographically projected onto the surface of the light absorption anisotropic layer and the absorption axis of the polarizer is 0° or greater and less than 85°, greater than 95° and less than 265°, or greater than 275° and 360° or less.
