A spatial light modulator and a method for driving the same.

摘要

The disclosed spatial light modulator includes a pair of facing transparent electrodes, and a light-modulating layer and a photoconductive layer provided between the transparent electrodes. In the spatial light modulator, the light-modulating layer has different optical states depending on an applied charge amount. Specifically, the light-modulating layer has: a first optical state when the applied charge amount is a first threshold charge amount or more; a second optical state when the applied charge amount is a second threshold charge amount or less; and a spatially uniform intermediate state between the first optical state and the second optical state depending on the applied charge amount. Also, a driving method for such a spatial light modulator is disclosed. <IMAGE>
