The present invention provides an organic electroluminescent device exhibiting a long life, a high luminance, and a high efficiency.
An organic electroluminescent device comprising on a substrate an anode, a hole transport layer, an organic light-emitting layer, and a cathode, wherein the organic light-emitting layer contains an organic compound having a pyridine ring, a pyrazine ring, or a triazine ring as a partial structure and the hole transport layer contains a monoamine compound represented by the following formula (I):
wherein R
1
to R
9
represent a hydrogen atom, an aryl group, or an alkyl group; R
1
to R
9
may be the same or different from each other; and R
1
to R
9
may further have an aryl group or an alkyl group as a substituent in the case where R
1
to R
9
are an aryl group or an alkyl group.
