A display apparatus including a light-emitting device is provided. The light-emitting device is disposed on a display area of a device substrate. An over-coat layer between the device substrate and the light-emitting device extends onto a bezel area. A moisture-blocking hole penetrating the over-coat layer is disposed on the bezel area. At least a portion of the moisture-blocking hole is filled by an encapsulating element disposed on the light-emitting device. A front adhesive layer covering the encapsulating element may attach an encapsulation substrate to the device substrate in which the light-emitting device and the encapsulating element are formed. A variable adhesive layer is disposed between the encapsulating element and the front adhesive layer and/or the over-coat layer and the front adhesive layer of the bezel area. Thus, in the display apparatus, the penetration of external moisture may be blocked, and the process efficiency and the productivity may be improved.

Display apparatus having a light-emitting device

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.

Electroluminescent display device

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.

Discussed is a display device capable of improving heat dissipation performance. The display device includes a display panel, and a back cover to support the display panel, wherein the back cover includes a first back cover stacked on the display panel and a second back cover stacked on the first back cover, where the back cover has thermal conductivity.
