Abstract: A display apparatus including a light-emitting device is provided. The light-emitting device may include a first electrode, a light-emitting layer and a second electrode, which are sequentially stacked on a display area of a device substrate. An over-coat layer may be disposed between the device substrate and the light-emitting device. The light-emitting layer, the second electrode and the over-coat layer may extend on a bezel area of the device substrate. A moisture blocking hole penetrating the over-coat layer of the bezel area may include a first blocking side having a positive tapered shape and a second blocking side having a negative tapered shape. A lower passivation layer between the device substrate and the over-coat layer may include a lower penetrating hole disposed between the first blocking side and the second blocking side. A reflective pattern overlapping with the second blocking side may be disposed between the device substrate and the lower passivation layer. A barrier pattern may be disposed on the first blocking side of the moisture blocking hole. The barrier pattern may extend inside the lower penetrating hole. Thus, in the display apparatus, the deterioration of the light-emitting layer due to penetration of external moisture may be effectively prevented.

Abstract: 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.

Abstract: An electroluminescent display device includes a substrate including an active area and a non-active area which encloses the active area, a planarization layer which is disposed on the substrate and extends from the active area to the non-active area, a bank over the planarization layer, an organic layer over the bank, a cathode over the organic layer, a trench pattern which is disposed in the non-active area and the cathode and the organic layer are removed and a step relieving layer which fills the trench pattern and is disposed to planarize an upper portion of the trench pattern to delay a moisture permeation speed from the side surface, thereby improving the reliability and reducing the bezel width at the same time.

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.
