Light emitting element, light emitting device and manufacturing method of light emitting element |
摘要 |
It is an object of the present invention to provide a light emitting element and a light emitting device having high luminous efficiency. It is a further object of the present invention to provide a method for manufacturing the light emitting element using a simplified method compared with the conventional method. A light emitting element having a light emitting region which includes plural kinds of materials with a high luminous quantum yield, and one or plural kinds of materials with a high carrier transporting property and which has a structure where regions in which the material with a high luminous quantum efficiency is dispersed in a material with a high carrier transporting property and regions in which the concentration of the material with a high carrier transporting property is high are laminated alternately, between a pair of electrodes, is provided.
