Abstract: A display apparatus may include a display panel that may include a display area in which a light-emitting device is disposed, and a bezel area disposed outside the display area. A device substrate may extend throughout the display area and the bezel area. An over-coat layer may be on the display area and the bezel area of the device substrate. The light-emitting device may include a first electrode, a light-emitting layer and a second electrode. A bank insulating layer covering an edge of the first electrode may extend on the over-coat layer of the bezel area. An opening penetrating the over-coat layer and the bank insulating layer may be on the bezel area of the device substrate. A sidewall of the opening may be covered by the second electrode. Thus, the penetration of external moisture through the over-coat layer and the bank insulating layer may be blocked or delayed.
