A light control device including an electro-optical material, a light refraction device mounted on the surface of the electro-optical material and electrodes provided on respective front and back major surfaces of the electro-optical material. A waveguide layer may be formed on the electro-optical material, with one electrode formed on an upper major surface of the waveguide layer and another electrode on the lower major surface of the electro-optical material. A prism or a diffraction grating may be used as the light refraction device. The light control device is particularly useful in laser printers and optical disk devices.
