Abstract: A display device includes a substrate including a plastic layer, a barrier layer, and a display area in which an image is displayed. The display device further includes a light-emitting diode disposed in the display area, a planarization layer, and a pixel definition layer. The planarization layer and the pixel definition layer overlap the light-emitting diode. The display device further includes a thin film encapsulation layer disposed on the pixel definition layer. The thin film encapsulation layer includes at least one inorganic layer. The display device further includes an opening disposed in the display area and penetrating the substrate. The opening includes a protruded portion and a depressed portion, and the barrier layer overlaps at least one of the pixel definition layer and the planarization layer at the protruded portion.

Abstract: A display device includes: a substrate including a display area at which an image is displayed with light, a non-display area which is adjacent to the display area, and a groove in the substrate, in the non-display area thereof; a light emitting element which generates and emits the light, disposed on the substrate in the display area thereof; and a common voltage transmitting line through which a common voltage is transmitted to the display area, disposed on the substrate in the non-display area thereof. The substrate further includes in each of the display area and non-display area thereof: a first insulating film, and a second insulating film disposed on the first insulating film. The groove extends into the second insulating film in a direction toward the first insulating film.
