Display device

The embodiment of the invention provides a display device, relates to the technical field of display, and is used for solving the heat dissipation problem of the display device. The display device comprises an optical assembly, a shell and a heat dissipation assembly. The optical assembly comprises a display module and a reflection module. The display module has a light emitting surface. The reflector group comprises a first lens and a second lens, the first lens is provided with a first reflecting surface, and the second lens is provided with a second reflecting surface; light emitted from the light emitting surface sequentially passes through the first reflecting surface and the second reflecting surface and then is emitted out of the shell. The housing is used for fixing the optical assembly. The heat dissipation assembly is connected with the shell and located on the side, away from the light emitting face, of the display module. The display surface device is used for displaying images. 本公开的实施例提供了一种显示装置，涉
