Abstract
The present invention provides a display, including a first display device, a second display device, a half mirror and a bifocal lens. The first display device provides a first image light, and the second display device provides a second image light. The half mirror has a first surface and a second surface opposite to each other, and is spaced apart from the first display device and the second display device by a first distance and a second distance respectively, where the first distance is not equal to the second distance. The first image light is emitted to the first surface, and the second image light is emitted to the second surface. The bifocal lens is spaced apart from the half mirror by a third distance and faces the first surface. The bifocal lens has a first focal length and a second focal length different from each other. The first focal length is greater than a sum of the first distance and the third distance, and the second focal length is greater than a sum of the second distance and the third distance.
