Abstract: A display device including a first substrate including a display area and a non-display area surrounding the display area, a second substrate disposed on the first substrate, a display element layer disposed on the second substrate and overlapping the display area, a first encapsulation layer disposed on the display element layer, overlapping the non-display area, and including an inorganic material, and a second encapsulation layer disposed on the first encapsulation layer, including a concavo-convex structure, and including an inorganic material. The first substrate includes a first surface overlapping an edge portion of the first substrate and facing the second substrate, and a first inclined surface extended to the first surface. An inclination angle formed by the first surface and the first inclined surface is an obtuse angle, and the first inclined surface overlaps the second encapsulation layer in a direction perpendicular to the first substrate.

Abstract: A display device includes a substrate, a first electrode disposed on the substrate, an organic light-emitting layer disposed on the first electrode, a second electrode disposed on the organic light-emitting layer, an encapsulation layer disposed on the second electrode, and a touch layer disposed on the encapsulation layer. The encapsulation layer includes a first inorganic layer, a first organic layer, a second organic layer, and a second inorganic layer. The first inorganic layer is disposed on the second electrode, the first organic layer is disposed on the first inorganic layer, the second organic layer is disposed on the first organic layer and has a greater ring parameter than the first organic layer, and the second inorganic layer is disposed on the second organic layer.
