Display apparatus having link wirings and at least one moisture blocking layer

A display apparatus comprising:

• a device substrate including a display area, a first bezel area, a second bezel area, a dam area, a third bezel area, a fourth bezel area, and a pad area that are disposed side by side in a first direction;
• an upper interlayer insulating layer on the display area, the upper interlayer insulating layer extending to the pad area;
• link wirings between the device substrate and the upper interlayer insulating layer, the link wirings disposed between the display area and the pad area;
• a power voltage supply line on the upper interlayer insulating layer, the power voltage supply line disposed between the display area and the pad area;
• a device protection layer on the upper interlayer insulating layer, the device protection layer covering the power voltage supply line;
• an encapsulating dam disposed on the dam area, the encapsulating dam crossing between the display area and the pad area in a second direction that intersects the first direction;
• a planarization layer disposed on the display area, the first bezel area, and the fourth bezel area of the device protection layer, the planarization layer spaced apart from the second bezel area, the dam area and the third bezel area;
• a first moisture blocking layer between the pad area and the dam area, the first moisture blocking layer overlapping a boundary between the third bezel area and the fourth bezel area;
• and
• a second moisture blocking layer between the dam area and the display area, the second moisture blocking layer overlapping a boundary between the first bezel area and the second bezel area.
