Display apparatus
First Claim
1. A display apparatus comprising:
- an image forming device; and
an optical device configured to guide an image from the image forming device to an eye of a viewer via a light reflecting member,wherein the optical device includes;
a first deflecting unit configured to deflect the image from the image forming device; and
a second deflecting unit configured to deflect the image deflected by the first deflecting unit, toward the eye of the viewer,wherein the light reflecting member is formed with an optical member including a first surface into and from which light from the image forming device is guided and emitted, and a second surface located on the opposite side from the first surface, a light reflecting layer being formed on the second surface,wherein the first surface and the second surface are formed with adjustable surfaces andwherein the adjustable surfaces are asymmetrical in an x-z plane and are symmetrical in a y-z plane, wherein an axis of the light reflecting member that extends through a light reflecting member incidence center point and is parallel to an axis of the optical device from the first deflecting unit to the second deflecting unit is an x-axis and a normal line of the light reflecting member that extends through the light reflecting member incidence center point is a z-axis, andwherein interference fringes are formed in at least one of the first deflecting unit and the second deflecting unit.

Abstract
A display apparatus includes: a frame 10 to be mounted on the head of a viewer; and an image display device 100 attached to the frame 10. The image display device 100 includes: an image forming device 111; and an optical device 120 that guides an image from the image forming device 111 to an eye of the viewer. The optical device 120 includes: a first deflecting unit 130 that deflects the image from the image forming device 111; and a second deflecting unit 140 that deflects the image deflected by the first deflecting unit 130, toward the eye 21 of the viewer. A light reflecting member 151 is further provided to face the image forming device 111, with the optical device 120 being interposed between the image forming device 111 and the light reflecting member 151. Light emitted from the image forming device 111 passes through the optical device 120, is reflected by the light reflecting member 151, reenters the optical device 120, and is deflected by the first deflecting unit 130.
