Abstract: A display apparatus including a light-emitting device is disclosed. The light-emitting device is on a display area of a device substrate. An overcoat layer is disposed between the device substrate and the light-emitting device. The overcoat layer extends on a bezel area of the device substrate. A heating signal wiring is between the bezel area of the device substrate and the overcoat layer. A heating pattern electrically connected to the heating signal wiring is on the over-coat layer of the bezel area. A surface of the heating pattern opposite to the device substrate may be in contact with an adhesive layer covering the light-emitting device. Thus, in the display apparatus, the damage of the light-emitting device due to external moisture may be prevented or at least reduced.

Abstract: An electroluminescent display device includes a display panel having a display area and a non-display area. A planarization layer is over the non-display area. A bank is on the planarization layer. An organic layer and a cathode are on the bank. A trench pattern extends through the cathode and the organic layer. An adhesive layer and an encapsulation substrate are disposed over the cathode. The adhesive layer covers the trench pattern. The adhesive layer is effective to slow a rate of moisture penetration to a side surface of the non-display area, allowing for improvements in reliability and a reduction in bezel width.

Abstract: An electroluminescent display device according to an exemplary embodiment of the present disclosure includes a display panel divided into a display area and a non-display area, a planarization layer and a bank extended to the non-display area of the display panel, an organic layer and a cathode disposed on the bank and extended to the non-display area of the display panel, a trench which is disposed in the non-display area outside the display area and from which the cathode, the organic layer, the bank and the planarization layer are removed; an under-cut structure which is disposed within the trench and composed of the bank and the planarization layer and in which the planarization layer retreats inwards from an end of the bank to generate an under-cut and an adhesive layer and an encapsulation substrate disposed on the cathode. Thus, reliability can be improved and a bezel width can be reduced.
