Abstract: A display panel includes: a substrate; a light emitting element array that is disposed above the substrate in an image display region; a peripheral electrode that is disposed above the substrate in a peripheral region, the peripheral region being located outside the image display region in plan view; a lyophilic insulating layer that is disposed on the peripheral electrode; and a peripheral bank that includes a liquid-repellent resin material including fluorine, and has an outer edge that overlaps the peripheral electrode in the peripheral region in plan view. The lyophilic insulating layer includes a resin material having a lower percentage of fluorine than the peripheral bank. At least a corner part of a bottom surface of the peripheral bank is disposed on the lyophilic insulating layer.
