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 16):
The virtual image display apparatus according to  claim 15 ,\n wherein the light guide member is formed of a pair of right and left light guide members, and the pair of right and left light guide members and the light transmissive member are so configured that the pair of right and left light guide members sandwich the light transmissive member and are connected each other via the light transmissive member to form a unitary optical member.
