Abstract: A display device includes an electrode, a protection layer disposed on the electrode, and an encapsulation organic layer disposed on the protection layer. In a first area, an edge of the encapsulation organic layer is spaced a first distance from an edge of the electrode, and the edge of the encapsulation organic layer is spaced a second distance from an edge of the protection layer. In the second area, the edge of the encapsulation organic layer is disposed between the edge of the electrode and the edge of the protection layer. In the second area, the edge of the encapsulation organic layer is spaced a third distance, greater than the first distance, from the edge of the electrode, and the edge of the encapsulation organic layer is spaced a fourth distance, greater than the second distance, from the edge of the protection layer.
