摘要： An organic luminescent element comprises a substrate, an organic electroluminescence element formed on one surface thereof and having a light-emitting section emitting light to the substrate, and a lens attached on the other surface of the substrate. A refraction index of the lens is ≧ that of the substrate. An area of the light-emitting section, parallel to the substrate's surface, is smaller than an area of the substrate on which the lens is attached. An angle θ between a line perpendicular to the substrate's surface in a direction from the light-emitting section toward the substrate and a straight line connecting an end of the light-emitting section and an end of the lens, is set to be ≧60°.
