To provide an organic electroluminescent display device including an organic electroluminescent layer that can be easily fabricated under an atmosphere containing oxygen and which can achieve high efficiency. An organic electroluminescent display device includes a substrate, an organic electroluminescent layer, an upper electrode and a lower electrode sandwiching therein the organic electroluminescent layer, either one of the upper and lower electrodes being a transparent electrode, and the other being a reflecting electrode, and a charge transport layer disposed between the organic electroluminescent layer and the substrate. The charge transport layer is photo-cured by light with a wavelength longer than that of a near-ultraviolet light.
