Patent ID: 7391575

Claim:
An image display apparatus comprising: first and second image display elements each of which displays an original image; and an optical system which introduces light beams from the first and second image display elements to first and second observation regions, respectively, wherein the optical system has a plane-symmetric structure whose plane of symmetry is a plane passing between the first and second observation regions, the first image display element and the first observation region being located in a first area on one side with respect to the plane of symmetry and the second image display element and the second observation region being located in a second area on the other side with respect to the plane of symmetry, the optical system introduces the light beam from the first image display element to the first observation region via a reflection on a reflecting surface located in the second area after a reflection on a reflecting surface located in the first area, and the optical system introduces the light beam from the second image display element to the second observation region via a reflection on a reflecting surface located in the first area after a reflection on a reflecting surface located in the second area.
