Abstract: A display device includes a substrate including a display area and a peripheral area, a driving element disposed in the display area on the substrate, a pixel electrode disposed on the driving element and connected to the driving element, a planarization layer including a first flat portion covering the driving element on the driving element and a first protrusion portion protruding in a thickness direction from an upper surface of the first flat portion adjacent to the pixel electrode, and a pixel defining layer disposed on the planarization layer. The pixel defining layer includes a bank portion, in which an opening is defined to expose a portion of the pixel electrode; and a spacer portion protruding in the thickness direction from an upper surface of the bank portion and spaced apart from the first protrusion portion in a plan view.
