PROBLEM TO BE SOLVED: To provide an organic electroluminescent display apparatus capable of reducing a chromaticity difference caused by light emission from an organic layer including an emission layer having the same color, which is continuously formed over two sub-pixels included in a pixel. SOLUTION: The organic electroluminescent display apparatus includes: a substrate; and multiple organic electroluminescent devices which are stacked on the substrate, each of which includes electrodes and an organic layer sandwiched by the electrodes in which first organic layer and a second organic layer are arranged side by side in an emission region corresponding to a pixel formed on the substrate and a third organic layer is stacked over the first organic layer and the second organic layer through an intermediate electrode. The third organic layer has an emission spectrum peak wavelength which is longer than an emission spectrum peak wavelength of at least one of the first organic layer and the second organic layer.
