ABSTRACT:
Disclosed is a displaying optical system including: a scanning member for deflecting a light emitted from a light source; a scanned surface on which an image is formed by the light deflected by the scanning member; an optical surface provided at a position common to a first optical path through which a light reflected by the scanned surface travels and a second optical path through which a light from the scanning member to the scanned surface travels; and a phase plate being provided at the position common to the first optical path and the second optical path. The optical surface, in accordance with a polarization direction, transmits the light traveling through one of the first optical path and the second optical path and reflects the light traveling through the other optical path.
