    Abstract: Disclosed is an organic EL display panel having pixels arranged in matrix includes a substrate, pixel electrodes disposed on the substrate for each of the pixels, insulating layers disposed so as to cover each upper part of the pixel electrodes and having not less than three slit-shaped openings extending and arranged in a column direction, partition walls extending in the column direction and partitioning the pixel electrodes in a row direction, organic functional layers disposed on the pixel electrodes and including organic luminous layers configured to cause electroluminescence in each of the openings, and light transmissive counter electrodes disposed on upper parts of the organic functional layers. Levels of top faces of the partition walls are higher than that of the insulating layers. Row-direction widths of openings adjacent to the partition walls in the row direction are larger than row-direction widths of openings not adjacent to the partition walls.

    Abstract: A display unit includes multiple pixels, a first electrode, a partition wall, a light emission layer, and a second electrode. The multiple pixels each have a light emission region and a non-light emission region along a first direction. The first electrode is provided in the light emission region in each of the multiple pixels. The partition wall is provided between each two of the pixels that are adjacent to each other in a second direction. The second direction intersects the first direction. The light emission layer covers the first electrode and is provided in the light emission region and the non-light emission region in a continuous manner. The second electrode faces the first electrode across the light emission layer.
