Abstract: A display apparatus includes: a substrate including a display area, and a peripheral area; and a pad unit at the peripheral area, the pad unit including: a first conductive layer; a second conductive layer on the first conductive layer, and having a first opening; a third conductive layer on the second conductive layer, and having a second opening overlapping with the first opening, the second opening having an area less than an area of the first opening at a top surface of the second conductive layer; an organic protective layer filling the first opening, and having a third opening overlapping with the second opening; and an additional metal layer covering a top surface of the first conductive layer exposed through the first opening, an inner surface of the second opening, an inner surface of the third opening, and a portion of a top surface of the third conductive layer.

Abstract: A display device includes: a substrate having an opening area, a display area at least partially extending around the opening area, and a middle area between the opening area and the display area; a light-emitting element in the display area, the light-emitting element including a pixel electrode, an opposite electrode, and a functional layer between the pixel electrode and the opposite electrode; a first separator in the middle area; a second separator between the first separator and the opening area; a first groove between the first separator and the second separator; and a first protective layer between the substrate and the first groove.
