摘要： A display device includes a display panel. A protective member is disposed below the display panel. A first adhesive layer is disposed on an upper surface of the protective member. The first adhesive layer includes a first coupling composition. A second adhesive layer is at least partially disposed between an upper surface of the first adhesive layer and a lower surface of the display panel. The second adhesive layer includes a second coupling composition different from the first coupling composition. The second adhesive layer has a creep characteristic greater than that of the first adhesive layer. An adhesive force of the first coupling composition to the protective member is greater than an adhesive force of the second coupling composition to the protective member.

摘要： A touch display apparatus is provided. The touch display apparatus may include touch electrodes on an encapsulating layer covering light-emitting devices. An auxiliary line crossing a display area in which the light-emitting devices are disposed may be disposed on the encapsulating layer. The auxiliary line may be electrically connected to a power voltage supply line at the outside of the display area. Each of the light-emitting devices may include a first emission electrode, a light-emitting layer and a second emission electrode, which are stacked on an emission area defined by a bank insulating layer. The second emission electrode of each light-emitting device may be electrically connected to the auxiliary line on the bank insulating layer. Thus, in the touch display apparatus, a luminance deviation due to a voltage drop may be prevented or at least reduced.

摘要： 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.
