    摘要： Provided is a light-emitting device exhibiting a high light-emission efficiency and moreover may utilize an external light radiating from the back side. A light-emitting device has a light-emitting element and a reflective layer reflecting light emitted from the light-emitting element. The reflective layer has a first layer constituted from a liquid crystal having a helical structure; a second layer disposed on opposite side of the first layer from the light-emitting element, and constituted from a liquid crystal having a helical structure with the same twisting direction as the first layer; and a third layer interposed therebetween to divide a light transmitted through the third layer itself into two intrinsic polarized lights causing a phase difference between the two intrinsic polarized lights.

    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°.
