A projection type liquid crystal display includes a light source, a reflective liquid crystal element modulating light from the light source based on an image signal, a polarization beam splitter disposed on an optical path between the light source and the liquid crystal element, a compensation plate disposed on an optical path between the liquid crystal element and the beam splitter, and projection means for projecting light impinging thereon through an optical path extending through the compensation plate and the beam splitter upon a screen, the light impinging upon the projection means after being modulated by the liquid crystal element. The compensation plate has in-plane retardation Re being one-fourth the wavelength of the incident light and retardation RthL in the thickness direction which is equal to retardation RthC in the thickness direction of the liquid crystal element in absolute value and is the reverse of the retardation RthC in polarity.
