ORGANIC ELECTROLUMINESCENCE DEVICE AND PHENYLENEDIAMINE DERIVATIVE |
摘要 |
An organic electroluminescence device having a low driving voltage and a long life and a material having a small ionization potential and providing a large hole mobility when used as a layer or region are disclosed. The organic electroluminescence device is characterized in that the device comprises a pair of electrodes and an organic luminescent layer sandwiched between the electrodes, a hole transport region between the electrodes contains a phenylenediamine derivative expressed by a specific structural formula and having a hole mobility of 10<-1> cm<2>/V•s or more when used as a material of a layer or region, and the organic luminescent layer contains a charge injection assisting material.
