Abstract

A display panel includes a base substrate, a first electrode contact portion, a light emitting layer, and a first electrode. The first electrode contact portion is disposed on the base substrate and surrounding a display area, and is separated from the display area by an isolation area. The light emitting layer covers the display area and at least a portion of the isolation area, and extends at least partially to an inner edge of the first electrode contact portion or a surface of the first electrode contact portion away from the base substrate. The first electrode is disposed on the light emitting layer and a portion of the first electrode contact portion that is not covered by the light emitting layer.
