Abstract: Disclosed are organic electroluminescent devices employing materials of a low reduction potential in a layer functioning hole-injection. The organic electroluminescent devices may employ an anode material having a relatively low work function. Aluminum may be used in anode. During the operation, the organic electroluminescent devices may form a virtual electrode in their internal area, which enhances injection of carriers from a nearby electrode. Use of aluminum in the anode helps construction of cathode-emission organic electroluminescent devices.

Abstract: Novel materials for electron injection/transportation and emitting layers can greatly improve the stability of an organic electroluminescent display. Electroluminescent displays incorporating these materials produce blue light at low voltage levels. These novel organic materials include compounds in which 1 to 2 imidazole functional groups are introduced in the 2 or 2,6-site of 9,10 substituted anthracene. An organic electroluminescent display with an organic compound layer of these materials has high efficiency, thermal stability, operationally stability and maintains driving voltage before and after operation.
