1. A spatial light modulation device, comprising:
- a light transmission substrate;
a liquid crystal layer;
a pixel array; and
a phase difference generation unit that is provided between the light transmission substrate and the liquid crystal layer to compensate for optical properties of a light beam passing through the liquid crystal layer,wherein the phase difference generation unit includes a polymer liquid crystal film with a fixed alignment obtained by cooling an aligned polymer liquid crystal film to a glass state.

Abstract
A spatial light modulator is disclosed that can be fabricated easily and is able to prevent degradation of a contrast ratio by suppressing a fringe effect. The spatial light modulator includes a light transmission substrate, a liquid crystal layer, a pixel array, and a phase difference generation unit provided between the light transmission substrate and the liquid crystal layer. A lens array is formed on the light transmission substrate, and the lens array has the same pitch as that of the pixel array.
