ABSTRACT:
There disclosed is an image display apparatus having a light source, a scanning member for deflecting a light from the light source to scan a predetermined surface with the light to form a two-dimensional image thereon, a first optical system for guiding a light deflected by the scanning member to the predetermined surface and a second optical system for guiding a light from the two-dimensional image formed onto the predetermined surface to an observer. There exists, in optical paths of the first optical system and the second optical system, a common optical element with a plurality of optical surfaces including refractive surfaces and reflective surfaces formed on a same medium and the first optical system and the second optical system share a part of optical surfaces of that optical element.
