DISPLAY APPARATUS
First Claim
1. A display apparatus comprising:
- (1) a frame;
(2) an image display apparatus attached to the frame; and
(3) a distortion correction apparatus,wherein the image display apparatus includes(A) an image forming apparatus and(B) an optical system configured to guide an image from the image forming apparatus to a pupil of an observer,when it is assumed that a direction, which corresponds to a first direction of the image, of the image forming apparatus is an X-direction and a direction, which corresponds to a second direction of the image which direction is different from the first direction, of the image forming apparatus is a Y-direction, the image forming apparatus is curved in the X-direction or the Y-direction, or in the X-direction and the Y-direction, andthe distortion correction apparatus corrects an input image signal to correct a distortion of the image to be observed.

Abstract
A display apparatus includes a frame, an image display apparatus attached to the frame, and a distortion correction apparatus. The image display apparatus includes an image forming apparatus and an optical system configured to guide an image from the image forming apparatus to a pupil of an observer. When it is assumed that a direction, which corresponds to a first direction of the image, of the image forming apparatus is an X-direction and a direction, which corresponds to a second direction of the image which direction is different from the first direction, of the image forming apparatus is a Y-direction, the image forming apparatus is curved in the X-direction and/or in the Y-direction. The distortion correction apparatus corrects an input image signal to correct a distortion of an image to be observed.
