Abstract: PROBLEM TO BE SOLVED: To provide a light-emitting diode provided with a substrate of a structure, capable of efficiently radiating the heat emitted from a light-emitting element to outside, without lowering the light-emitting characteristics of the light-emitting element. SOLUTION: The light emitting diode 21 is provided with a flexible substrate 22 where an anode electrode 25a and a cathode electrode 25b are formed, and the light-emitting element 23 mounted on the surface of the flexible substrate 22. On the flexible substrate 22, a seating part 26 for the light-emitting element 23 which is obtained by making the flexible substrate 22 project from a rear face side toward the front face side is provided to form a recessed place 28 on the rear surface of the seating part 26, and the recessed place 28 is charged with a radiation member 31.

TL;DR: By doping an organic compound functioning as an electron donor (hereinafter referred to as donor molecules) into an organics layer contacting a cathode, donor levels can be formed between respective LUMO (lowest unoccupied molecular orbital) levels between the cathode and the organic compound layer, and therefore electrons can be injected from the cathodes, and transmission of the injected electrons can also be performed with good efficiency as discussed by the authors.
