An organic electroluminescent display which has excellent partiality, and which includes a substrate, an electrode provided on the substrate, and protrusions provided on the substrate so as to cover the ends of the electrode and convexly curved in section relative to the surface of the substrate. An electroluminescent layer is provided in each opening which is located on the electrode and defined by adjacent protrusions. The electroluminescent layer in its part around the boundary between the electroluminescent layer and the protusion is in contact with the protrusion can be in such a state that the electroluminescent layer is curved in section in a direction opposite to the convexly curved protrusion.
