Abstract
In a spatial light modulation device using a reflection type spatial light modulator, read light is a P-polarized light that falls incident on the light reflection layer at a slant. Liquid crystal in the light modulation layer is oriented so as to incline, in association with the application of voltage by the driving circuit , within a plane that is parallel to a normal plane which includes the optical axes of both of the incident, read light and the output, modulated light.
