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.
