ABSTRACT:
An organic electroluminescent device comprises an anode, a positive-hole transport layer, an emitting layer, (an electron transport layer) and a cathode which are layered in sequence, wherein the emitting layer (and/or the electron transport layer) comprises at least one of dioxazine compounds or diazine compounds. The emitting capability of the organic electroluminescent device is improved in luminance and efficiency upon application of a low voltage.
