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 2):
The virtual image display apparatus according to  claim 1 ,\n wherein the video device generates the video image light from a rectangular region, and in the projection system, the one nonaxisymmetric aspheric surface is located in a position where in a pencil of light of video image light that exits from each of four corners of the rectangular region of the video device, light components that should reach the viewer's eyes do not intersect each other.
