Abstract

A self-luminous display panelin which self-luminous elementsare arranged on a plane, wherein each of the self-luminous elements includes: a pair of electrodesdisposed facing each other, an electrode of the pair of electrodes including a metal layerA; functional layersincluding a light emitting layer, disposed between the pair of electrodes; and a sealing layerthat covers the pair of electrodes and the functional layers from a direction. The self-luminous elements include a repaired self-luminous element′. The repaired self-luminous element includes a foreign object FO among the functional layers. The electrode including the metal layer has a high resistance portionsurrounding, in plan view, an area containing the foreign object, and has a thickened portionof the metal layer at an outer edge, in plan view, of the high resistance portion.
