ORGANIC ELECTROLUMINESCENCE ELEMENT

摘要

An organic electroluminescence element comprising: a hole transport layer which contains a tri(p-terphenyl-4-yl)amine represented by the general formula (I) as a hole transporting agent; and a hole injection layer which contains a hole injecting agent comprising an aromatic tertiary amine having an ionization potential ranging from 5.2 to 5.6 eV. The organic electroluminescence element can operate at a low operation voltage, with high efficiency and at a high luminance. (I) wherein R¹, R² and R³ independently represent a hydrogen atom, an alkyl group, a cycloalkyl group which may have a substituent, or an aryl group which may have a substituent.
