Abstract

A display panel includes a circuit layer on a base substrate, a first electrode and an auxiliary electrode disposed on the circuit layer, and spaced apart from each other, a charge generation layer on the first electrode and the auxiliary electrode, a first opening region being defined in the charge generation layer, a second electrode on the charge generation layer, a first organic layer disposed between the first electrode and the charge generation layer, a second opening region being defined in the first organic layer, and a second organic layer disposed between the charge generation layer and the second electrode, a third opening region being defined in the second organic layer. The second electrode is electrically connected to the auxiliary electrode through the first to third opening regions, and the second organic layer includes a protrusion adjacent to the third opening region.
