Abstract: A display device includes an insulating layer disposed on a substrate, a pixel electrode including a first conductive layer, a second conductive layer, and a third conductive layer sequentially stacked on the insulating layer, a pixel defining layer covering the pixel electrode and partially exposing the pixel electrode through an opening, an organic light emitting layer disposed in the opening of the pixel defining layer, and an opposing electrode disposed on the organic light emitting layer and overlapping the pixel electrode. A length of the first conductive layer is less than a length of the second conductive layer.
