Abstract
A light modulator element includes a liquid crystal element which has a liquid crystal layer containing liquid crystal molecules aligned along a first direction, and two transparent electrodes disposed in opposition to each other with the liquid crystal layer sandwiched therebetween, and which controls the phase of linear polarization light and passing through said liquid crystal layer by applying an electric voltage between said two transparent electrodes; a polarizer plate which is disposed between a light source and said liquid crystal element and which has the transmission axis along the first direction or along a direction orthogonal to said first direction; and a rotation mechanism which supports the liquid crystal element and the polarizer plate and which rotates the liquid crystal element and the polarizer plate integrally in one unit with the optical axis of the liquid crystal element as the rotation axis.
