| titleOfInvention | High efficiency organic light emitting device |
| abstract | In the light emitting device of the conventional resonator structure, since there is little freedom in adjusting the thickness of the electron transporting layer to adjust the charge balance of the light emitting device, it is almost impossible to adjust the phase of the electromagnetic wave when it comes out of the light emitting layer and reflects back to the metal electrode. It was impossible. In addition, since a material having an excitation relaxation time longer than a few microseconds diffuses long-distance from the light emitting layer until the excited state is relaxed, the excited state reached on the metal electrode in the conventional resonator structure is deactivated. High brightness and high efficiency cannot be achieved.n n n A transparent conductive film is used for both the anode 202A and the cathode 202B of the organic light emitting element having the hole transport layer 203, the light emitting layer 204, the electron transport layer 205, and the electron injection layer 206. By providing the film 201 and 207 which have a light reflection function on the outer side, and having the structure which functions as an optical resonator between them, the organic light emitting element which solved the said two subjects simultaneously can be obtained.n n n In the organic light-emitting device, it is possible to introduce a high efficiency, a prevention of a decrease in efficiency on the high luminance side, and a resonator effect.n n n n Organic light emitting element, hole transport layer, light emitting layer, electron transport layer, electron injection layer, transparent conductive film, light reflecting film, resonator |
