ABSTRACT:
The present invention relates to an image display apparatus disposed near an observer's head for observing an image displayed on image display means as an enlarged virtual image. The apparatus has a relay optical system for causing the displayed image by the image display means to be intermediately formed, the relay optical system having at least one decentered reflecting surface for bending a light beam from the image display means, and at least one lens of an anamorphic aspherical shape differing in curvature in any orthogonal direction, and an eyepiece optical system for directing the image by the relay optical system to the observer's pupil, the eyepiece optical system having at least one decentered reflecting surface which is an anamorphic aspherical surface of a concave surface shape for bending the light beam from the relay optical system.
