A display device comprises: a display panel; a rear surface panel coupled to the display panel by means of a first adhesive tape partially coated onto a rear surface of the display panel; a rigid bar which is arranged between the display panel and the rear surface panel and coupled to the rear surface of the display panel by means of a second adhesive tape, such that it is possible to provide a display device having sufficient rigidity while minimizing increase in thickness and reducing the weight of a structure for supporting the rear surface of the display panel by simultaneously using the rear surface panel and the rigid bar on the rear surface.
