LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, AND ELECTRONIC DEVICE

摘要

Disclosed is a light-emitting element with a good carrier balance and manufacturing method thereof which does not require the formation of the heterostructure. The light-emitting element includes an organic compound film containing a first organic compound as the main component (base material) between an anode and a cathode, wherein the organic compound film is provided in contact with the anode and with the cathode. The first organic compound further includes a light-emitting region to which a light-emitting substance is added and includes a hole-transport region to which a hole-trapping substance is added and/or an electron-transport region to which an electron-trapping substance is added. The hole-transport region is located between the light-emitting region and the anode., and the electron-transport region is located between the light-emitting region and the cathode.
