Abstract: A display panel includes a base layer, and a light emitting element layer having a plurality of light emitting regions spaced apart from each other and a non-light emitting region. The light emitting element layer includes a first electrode, a pixel-defining film, a hole transport region, a light emitting layer to correspond to the plurality of light emitting regions, an electron transport region, and a second electrode. The electron transport region integrally overlaps the plurality of light emitting regions and the non-light emitting region, and the hole transport region does not overlap at least a portion of the non-light emitting region.
