Abstract: An organic EL display panel includes a substrate, pixel electrodes, a current feeding auxiliary electrode layer provided to extend in a column direction over gaps between the pixel electrodes adjacent in a row direction, light emitting layers that each contain an organic light emitting material and are disposed over the pixel electrodes, a functional layer provided ranging over the light emitting layers and over the current feeding auxiliary electrode layer, and a common electrode layer provided continuously over the functional layer. A part of the functional layer is lacking or thinned. The common electrode layer is in direct contact with the current feeding auxiliary electrode layer exposed due to the lacking of the functional layer, or is electrically connected to the current feeding auxiliary electrode layer at a lower resistance at the thinned part of the functional layer than at other parts of the functional layer.

Abstract: A light-emitting panel includes a plurality of pixels, a plurality of first regulators, and a plurality of second regulators. The plurality of first regulators extends in a first direction and defines each two of the pixels that are adjacent to each other in a second direction orthogonal to the first direction. The plurality of second regulators extends in the second direction and defines each two of the pixels that are adjacent to each other in the first direction. The plurality of pixels at least includes a first pixel and a second pixel that have different lengths in the first direction from each other and share a light-emitting layer. The first pixel and the second pixel are at least adjacent to each other in the first direction with the second regulator being interposed between the first pixel and the second pixel.
