Abstract: A display device according to the present disclosure includes a substrate divided into a display area and a non-display area, an inorganic insulating layer and a planarization layer disposed over the substrate, a light emitting element disposed over the planarization layer and comprising an anode, an organic layer, and a cathode, an outer dam disposed over the substrate in the non-display area so as to enclose the display area, a plurality of inner dams disposed in the display area and a back cover which maintains a gap by the outer dam and the inner dam and is vacuum-bonded to the substrate, and a bonding layer and an encapsulation substrate required for an encapsulation can be eliminated, thereby reducing the consumption of raw materials for the bonding layer and the encapsulation substrate, and reducing process costs by omitting of a process for encapsulation.
