Abstract
A display device includes a bending area at which the display device is bendable; an organic light emitting element disposed on the substrate; an encapsulation layer covering an upper surface and a side surface of the organic light emitting element; and a bending area protection layer covering the bending area of the substrate. The upper surface of the encapsulation layer includes a nano structure defined by nano sized protrusions and depressions of the upper surface, and along the substrate, and the bending area is disposed separated from the encapsulation layer.
