Abstract: A light-transmissive organic EL display panel including: a light transmissive substrate; organic EL elements on the substrate, where pixels each including a plurality of organic EL elements arranged along a row direction are arranged in pixel columns arranged in parallel along the row direction, and intervals between the pixel columns are each greater than a width in the row direction of any of the pixel columns; and dummy light emitting layers, wherein each of the organic EL elements included in one of the pixels includes any one of a plurality of organic light emitting materials that emit different colors of light, and the dummy light emitting layers include any one of the plurality of organic light emitting materials and are present above portions of non-pixel regions adjacent to the pixel columns in the row direction.

Abstract: A method of manufacturing an organic electroluminescence display panel including: preparing a substrate; forming pixel electrodes arranged in a matrix above the substrate; forming parallel column banks above the substrate in spaces between the pixel electrodes in a row direction; forming functional layers including organic light emitting layers in gaps between the column banks, including causing relative motion in the row direction between the substrate and a head provided with nozzles arranged along a column direction while ejecting ink from selected nozzles among the nozzles to supply a set of the gaps with an ink including an organic material; and forming a counter electrode above the functional layers. Among the set of the gaps, nozzle patterns of the selected nozzles for a gap differ between a first gap and a second gap in a sequence in the row direction of the set.

Abstract: An organic EL display panel including a substrate, an element array, a planarizing layer, light emitting layers, and a dummy light emitting layer. The element array is disposed above the substrate and includes a light emitting region and a peripheral region that does not emit light surrounding the light emitting region. The planarizing layer is disposed between the substrate and the element array so as to cover the substrate. The light emitting layers are present in the element array in the light emitting region and include organic light emitting material. The dummy light emitting layer is present in the element array in the peripheral region and includes organic light emitting material. A portion of the planarizing layer below the dummy light emitting layer is recessed, and a lower portion of the dummy light emitting layer extends inside the recessed portion.
