1. A display device comprising:
a base layer comprising a display area and a non-display area disposed at an outer side of the display area on a plane;
a first electrode disposed on the display area;
a light emitting layer disposed on the first electrode;
a second electrode that overlaps the display area and the non-display area and is disposed on the light emitting layer;
a protection layer that overlaps the display area and the non-display area and is disposed on the second electrode; and
a thin-film encapsulation layer that overlaps the display area and the non-display area, is disposed on the protection layer, and comprises an encapsulation organic layer,
wherein the non-display area comprises a first area and a second area,
in the first area, an edge of the encapsulation organic layer is spaced a first distance from an edge of the second 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 second electrode and the edge of the protection layer,
in the second area, the edge of the encapsulation organic layer is spaced a third distance from the edge of the second electrode, and the edge of the encapsulation organic layer is spaced a fourth distance from the edge of the protection layer,
the third distance is greater than the first distance, and
the fourth distance is greater than the second distance.
