Abstract: A display panel includes a contact area which includes an upper conductive layer forming first electrodes of the organic EL elements, a lower conductive layer disposed below the upper conductive layer, a middle layer between the upper conductive layer and the lower conductive layer, and an insulating layer between the lower conductive layer and the middle layer. The middle layer includes a first area and a second area which are conductive and electrically connected to the upper conductive layer, and an insulating separating area which separates the first area and the second area. The lower conductive layer includes a first line which is electrically connected to the first area via a first contact hole, and a second line which is electrically connected to the second area via a second contact hole.

Abstract: A display panel including auxiliary wiring on a substrate, pixel electrodes in a matrix above the substrate with gaps between the pixel electrodes, light emitting layers above the pixel electrodes, a functional layer above and continuous across the light emitting layers, and a common electrode above and continuous across the functional layer. The auxiliary wiring extends in plane directions of a main surface of the substrate below the pixel electrodes. Above the substrate, connection areas CA exist where the pixel electrodes are not present, in which the common electrode and the auxiliary wiring are electrically connected to each other. In plan view, portions of outer edges of the pixel electrodes facing outer edges of the connection areas CA are recessed inwards of the pixel electrodes.
