Abstract: A display device includes, a display panel including a light-emitting element layer disposed on a substrate, a thin-film encapsulation layer disposed on the light-emitting element layer, a touch electrode layer disposed on the thin-film encapsulation layer, a display area, the light-emitting element layer being located in the display area, and a non-display area disposed around the display area, and a resin pattern disposed on and directly contacting the touch electrode layer. The non-display area includes a first non-display area disposed around the display area, and a second non-display area spaced apart from the display area, the first non-display area being disposed between the display area and the second non-display area in a plan view. The resin pattern is disposed in the second non-display area in a plan view.
