Abstract

A liquid crystal projector (200) forms full color images by compositing three primary color light beams passed through liquid crystal devices for RGB (311R, 311G, 311B). In a light path of each liquid crystal device, a phase difference compensation element (400) is placed. The phase difference compensation element (400) includes a first optical anisotropic layer (401), which is made from an inorganic material and composed of high refractive index layers (401a) and low refractive index layers (401b), and a second optical anisotropic layer (402) including a polymerizable liquid crystal compound whose liquid crystal molecules are oriented to form hybrid orientation along the thickness direction of the liquid crystal device. The first and second optical anisotropic layers are adjusted in thickness (d1, d2) according to primary color light beams of RGB passing through the liquid crystal devices.
