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.
