发明名称 LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, DISPLAY DEVICE, AND ELECTRONIC APPARATUS
摘要 A light-emitting element includes an anode; a cathode; a first light-emitting layer that is disposed between the anode and the cathode, the first light-emitting layer emitting light in response to application of voltage between the anode and the cathode; a second light-emitting layer that is disposed between the cathode and the first light-emitting layer, the second light-emitting layer emitting light in response to application of voltage between the anode and the cathode; and a carrier-generating layer that is disposed between the first light-emitting layer and the second light-emitting layer, the carrier-generating layer generating electrons and holes. The carrier-generating layer has an n-type electron transport layer and an electron-withdrawing layer, the n-type electron transport layer contacting the first light-emitting layer and having electron transportability, and the electron-withdrawing layer being disposed between the n-type electron transport layer and the second light-emitting layer and having electron-withdrawing properties.
