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...http://www.google.com.au/patents/US20040113547?utm_source=gb-gplus-sharePatent US20040113547 - Electroluminescent devices with low work function anode
