THIN-FILM LIGHT EMITTING DEVICE COMPRISING CHARGE ELECTRON TRANSPORT LAYER AND MANUFACTURING METHOD THEREOF

摘要

The present invention provides a thin-film light emitting device and a manufacturing method thereof. The thin-film light emitting device comprises: a cathode; at least one light emitting unit formed in the cathode and sequentially including an electron injection layer, an electron transport layer, a thin-film light emitting layer, a hole transport layer and a hole injection layer; and an anode formed on the at least one light emitting unit, wherein the electron transport layer is characterized in that alkali metal carbonate is blended with a zinc oxide.
