Abstract: A display device is disclosed. A display device according to one embodiment of the present disclosure includes: a case in which an opening is formed; a first optical mirror disposed in a first side of the case; and a second optical mirror disposed in a second side of the case and located below the first optical mirror, wherein a curved surface is formed on the first optical mirror, and a residual, which is a difference between the curved surface of the first optical mirror and a parabolic surface, is asymmetric at both ends of the first optical mirror. Accordingly, it is possible to provide a display device capable of improving a viewing angle for displaying a floating image.
