Original Abstract Submitted
a light-emitting device that can be used in a high-resolution display apparatus and has a low driving voltage and high current efficiency is provided. a tandem light-emitting device is fabricated through a photolithography process and includes a plurality of light-emitting units and an intermediate layer therebetween. the intermediate layer includes a layer that includes a metal oxide and an organic compound having a phenanthroline ring with an electron-donating group. the layer of the intermediate layer is in contact with a light-emitting unit on the anode side.
