Abstract: A display device includes a substrate including a display area in which subpixels are disposed and a non-display area which includes a pad area located in a first direction from the display area; an insulating layer stack located on the substrate, and having an outer side surface; a cathode located on the insulating layer stack, and disposed to extend from the display area to the non-display area; a first inorganic layer located on the cathode, and disposed to extend from the display area to the non-display area; an organic layer located on a part of the first inorganic layer, and having an outer sloped surface; a second inorganic layer located on the organic layer, disposed to extend from the display area to the non-display area, and disposed to extend along the outer sloped surface; and a stopper located on the insulating layer stack, and disposed outside the organic layer.

Abstract: An electroluminescent display device can include a substrate divided into a plurality of sub-pixels having an opening area and a non-opening area, a planarization layer disposed on the substrate, an anode disposed on the planarization layer, and a bank disposed on the anode and the planarization layer, the bank having an opening exposing a portion of the anode in the opening area. The electroluminescent display device has a light emitting unit disposed on the portion of the anode; a cathode disposed on the light emitting unit and the bank. A deposition blocking layer is disposed on the cathode in a portion of the non-opening area and the opening area, and a reflective layer disposed on the cathode in another portion of the non-opening area, in which the reflective layer does not overlap with the deposition blocking layer.
