摘要： 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.

摘要： A display unit includes a plurality of light-emitting sections and an optical filter. The plurality of light-emitting sections emit color light beams having different colors. The optical filter is disposed on light emission side of the plurality of light-emitting sections, and transmits the color light beams while selectively removing a part of a wavelength band of the color light beams. The optical filter includes the first filter layer and the second filter layer. The first filter layer transmits a first band including a center wavelength out of the wavelength band of each of the color light beams, and removes a second band that is at least a part of a band other than the first band. The second filter layer reduces transmissivity of a third band that is a part of the first band of at least one color light beam out of the color light beams.
