Abstract: A display device including: a substrate; a plurality of display elements defining a display area on the substrate and each including a pixel electrode, an opposite electrode, and an intermediate layer between the pixel electrode and the opposite electrode; a power supply wiring disposed outside the display area; an organic insulating layer on the power supply wiring and having an opening exposing the power supply wiring; a power supply electrode layer partially disposed on the organic insulating layer and including a plurality of holes over the organic insulating layer. A first portion of the power supply electrode layer overlaps the power supply wiring and a second portion of the power supply electrode layer overlaps the opposite electrode; a plurality of protrusions spaced apart from each other and respectively covering at least some of the plurality of holes; and an encapsulation layer covering the plurality of display elements.
