Abstract
A display device includes a substrate having a plurality of sub-pixels, a first overcoating layer disposed on the substrate, a second overcoating layer including a bottom surface layer disposed on the first overcoating layer and a protruding portion protruded at least partially from the bottom surface layer, an anode disposed on a top surface of the protruding portion of the second overcoating layer, an organic layer disposed on the anode, and a cathode disposed on the organic layer corresponding to the top surface and the side surface of the protruding portion, in which a refractive index of the first overcoating layer is smaller than a refractive index of the second overcoating layer.
