An image displaying apparatus employs quartz wave plates and displays images of high contrast. The quartz wave plates in the image displaying apparatus are each arranged between a polarizing beam splitter of a color separating-combining unit and a reflective spatial light modulator. Each of the quartz wave plates is made of two elementary quartz plates. An angle formed between slow axes of the two elemental quartz plates is within a range of 5 minutes to 15 minutes from a right angle.
