Abstract: A display panel includes a pixel region and a non-pixel region adjacent to the pixel region, and a light-emitting element layer disposed on a base layer. The light-emitting element layer includes a first electrode disposed on the base layer, a pixel defining film disposed on the base layer and having pixel openings corresponding to the pixel region, a heating line disposed on the pixel defining film, an organic layer including a light-emitting layer and disposed on the first electrode, and a second electrode disposed on the organic layer. The heating line is disposed in the non-pixel region and surrounds the pixel region in a plan view, thereby improving reliability and processability.
