Zusammenfassung: | To provide an organic EL display that has an excellent external light reflection suppressing effect, high emission luminance, and high reliability of a light emitting element.SOLUTION: A display device has a first electrode, a second electrode, a pixel dividing layer, an organic layer including a light emitting layer, a sealing layer, a color filter layer, and a black matrix layer on the same substrate. The pixel dividing layer contains a (D-DL) colorant, and the optical density at the wavelength of visible light per 1 μm of film thickness of the pixel dividing layer is 0.5 to 3.0. In plan view, the display device has a plurality of pixel portions, and the shape of the pixel portion satisfies one of the following conditions (1a), (2a), and (3). (1a) The shape is a closed polygon containing at least 5 sides. (2a) The shape is a shape obtained by replacing at least some of the sides and/or vertices with circular arcs from the closed polygon containing at least 5 sides. (3) The shape is a closed shape formed with a circular arc.SELECTED DRAWING: Figure 4
