Light-Emitting Element, Light-Emitting Device, and Lighting Device |
摘要 |
Disclosed is a light-emitting element with a microcavity structure which is capable of amplifying a plurality of wavelengths to give emission of a desired color. The light-emitting element includes a pair of electrodes and an EL layer having a light-emitting substance interposed between the pair of electrodes. One of the pair of electrodes gives a reflective surface and the other electrode gives a semi-reflective surface. The light-emitting element is arranged so that the emission of the light-emitting substance covers at least two wavelengths λ and an optical path length L between the reflective surface and the semi-reflective surface satisfies an equation L=nλ/2 where n is an integer greater than or equal to 2. |
