Patent ID: 7145706

Claim:
An image displaying apparatus, comprising: a light source; a scanning member for two-dimensionally scanning with light from the light source; and an optical system for directing the light deflected by the scanning member for scanning to an observer, the optical system being provided with an optical element in which a plurality of optical surfaces including refracting surfaces and internal reflecting surface are formed on a medium, wherein the refracting surfaces include an incidence surface on which the light deflected by the scanning member is directly incident and an emergence surface from which the light via the internal reflecting surface exits, wherein the light deflected by the scanning member for scanning forms a two-dimensional image on a predetermined surface through a portion of the plurality of optical surfaces of the optical element; and wherein the plurality of optical surfaces formed in the optical element are disposed so that an effective area of the incidence surface and an effective area of the internal reflecting surface do not overlap each other.
