Image display apparatus and head mounted display
First Claim
1. A head mounted display comprising:
- (a) a frame shaped like glasses to be worn on the head of an observer; and
(b) an image display apparatus attached to the frame, the image display apparatus including(A) an image forming device;
(B) an optical system that converts light emitted from the image forming device into parallel light; and
(C) an optical device to which the light beams converted into the parallel light by the optical system enter, in which the light beams are guided, and from which the light beams are emitted,wherein when a point where a central light beam that is emitted from the center of the image forming device and passes through the nodal point of the optical system on the side of the image forming device enters the optical device is defined as an optical device center point, an axis that passes through the optical device center point, and is parallel to the axis direction of the optical device is defined as an X-axis, and an axis that passes through the optical device center point, and coincides with the normal axis of the optical device is defined as a Y-axis,the central light beam intersects the XY plane at angles other than 0 degree.

Abstract
An image display apparatus includes: an image forming device; an optical system converting light emitted from the image forming device into parallel light; and an optical device to which the light beams converted into the parallel light by the optical system enter, in which the light beams are guided, and from which the light beams are emitted, wherein a central light beam emitted from the center of the image forming device, passing through the nodal point of the optical system and entering the optical device at an optical device center point intersects an XY plane defined by an X axis that passes through the optical device center point, and is parallel to the axis direction of the optical device and a Y axis that passes through the optical device center point, and coincides with the normal axis of the optical device at angles other than 0 degree.
