An organic luminescent element comprises a substrate 2, an organic electroluminescence element 3 formed on one surface of the substrate 2 and having a light-emitting section 5 emitting light to the substrate 2, and a lens 1 attached on the other surface of the substrate 2. A refraction index of said lens is more than or equal to that of the substrate 2. An area of a face of the light-emitting section 5, parallel to the substrate's surface, is smaller than an area of the substrate 2, on which the lens 1 is attached. An angle ¸ between a line L±, perpendicular to the substrate's surface 2a in a direction from the light-emitting section 5 toward the substrate 2, and a straight line L1, connecting an end of the light-emitting section 5 and an end of the lens 1, is set to be more than or equal to 60°. |
