Abstract: An image display apparatus includes a light source for supplying illumination light, a reflection type display element for modulating the illumination light into image light by reflecting the light, an illumination optical system for guiding the illumination light to the reflection type display element, and a projection optical system for guiding the image light to an observer. The image light is incident on the projection optical system via at least a portion of the illumination optical system. The illumination optical system has a part, in an area where both the illumination light and the image light pass, which changes an optical action depending on a state of incident light. The part acts to deflect the illumination light to decrease an incident angle with respect to the reflection type display element as compared with a case where the part does not exist.

Abstract: An image display apparatus includes a light source for supplying illumination light, a reflective display element for reflecting and modulating the illumination light into image light, a first optical system for guiding the illumination light to the reflective display element, and a second optical system for guiding the image light to an observer. Particularly, the first optical system has an optical element including a first surface on which the illumination light is incident, a second surface for totally reflecting the light incident on the first surface, and a third surface from which the light totally reflected by the second surface emerges toward the reflective display element. The first optical system is arranged so that the image light is again incident through the third surface on the optical element and emerges from the second surface toward the second optical system. The optical element has a function of preventing unnecessary light from being guided to the observer, by making a side surface of the optical element as a diffusing surface, or by providing a side surface of the optical element with a light absorbing film or with an antireflection coating.
