ABSTRACT:
A scan type display optical system is disclosed in which the position and inclination of an image formed by projection light is made variable. The scan type display optical system comprises an optical scanning member for deflecting and scanning light, and a projection optical system which includes a plurality of optical surfaces containing a reflective surface. The projection optical system projects light from the optical scanning member. An incidence range of light from the optical scanning member to a first optical surface on which the light is incident initially out of the plurality of optical surfaces is variable.
