摘要： A head-mounted display includes an image forming part, a half mirror reflecting a part of an image light emitted by the image forming part toward an optical pupil position, and a wall part. Given that an intersection point between the half mirror and an optical axis of the image light is defined as a first intersection point, an intersection point between the wall part and the optical axis is defined as a second intersection point, a distance between the first intersection point and the second intersection point is defined as a first distance, and an angle at which the wall part inclines with respect to the optical axis is defined as a first angle, the first angle and the first distance are set such that the image light passed through the half mirror and reflected by the wall part reaches a position different from an optical pupil position.
