A phase compensation element is disposed between a reflective type display element and a polarizing beam splitter. Composed of a crystal structure retardation layer functioning as a quarter-wave plate and an inclined-axis retardation layer functioning as an O-plate, the phase compensation element is aligned substantially parallel to a reflective surface of the reflective type display element. The inclined-axis retardation layer is made of inorganic material obliquely deposited on the crystal structure retardation layer. The inclined-axis retardation layer has a principal refractive index axis inclined at between 0° and 45° to a surface normal of the crystal structure retardation layer, and has a thickness not to increase haze of the phase compensation element.
