[Objective]To increase the outgoing efficiency of light generated in an organic luminous layer of an organic electroluminescence element without decreasing the numerical aperture. [Problem Resolution Means]A light-transmissive anode electrode layer 3, an organic luminous layer 4, and a light-reflective cathode layer 5 are let exist on the whole surface of one pixel region. On the anode layer 3, the organic luminous layer 4, and the cathode layer 5, slopes 62~64 are installed protruding from the anode layer 3 side to the cathode layer 5 side. By this, light H generated in the organic luminous layer 4 and irradiated in parallel to a cumulate surface of a cumulate body S is reflected by the slope 63 on the boundary between the organic luminous layer 4 and the cathode layer 5 and let go out toward the anode layer 3 side.
