A display apparatus including link wirings is provided. The link wirings may be between a display area and a pad area of a bezel area. An upper interlayer insulating layer and a device protection layer may be disposed on the link wirings. A power voltage supply line between the display area and the pad area may be disposed between the upper interlayer insulating layer and the device protection layer. An encapsulating dam and an upper planarization layer may be disposed on the device protection layer. The encapsulating dam may cross between the display area and the pad area. The upper planarization layer may be disposed outside a dam area overlapping with the encapsulating dam. A first moisture blocking layer may be disposed between the pad area and the encapsulating dam. A second moisture blocking layer may be disposed between the encapsulating dam and the display area. The first moisture blocking layer and the second moisture blocking layer may overlap an end of the upper planarization layer.
