摘要:
An organic electroluminescent device includes an anode, a cathode, a luminescent layer disposed between the anode and the cathode, and a hole-transporting layer disposed between the anode and the cathode. The luminescent layer includes a first sublayer made of a first metal complex and a second sublayer made of a second metal complex. The second sublayer is disposed further from the hole-transporting layer than the first sublayer.
