Abstract:
In a projection system, a nonaxisymmetric aspheric surface is used as a surface that is located in a position where in a pencil of light of video image light that exits from each of two points in different corner regions in an image plane that is a light exiting plane of an image display apparatus, light components that should reach a viewer's eyes do not intersect one another, whereby the size of an optical system can be further reduced and the size of an overall apparatus can therefore be reduced with a variety of types of optical precision, such as the resolution and angle of view, maintained.

Claim (Index 6):
The virtual image display apparatus according to  claim 5 , wherein the projection system has a stop that forms an opening that is not only so located as to be orthogonal to a lens optical axis passing through a center of the video device and parallel to the direction of the normal but also symmetric with respect to a first axis that extends in parallel to the first direction and intersects the lens optical axis but asymmetric with respect to a second axis that extends in parallel to the second direction and intersects the lens optical axis or an opening that is so disposed as not to be orthogonal to the lens optical axis.
