PROBLEM TO BE SOLVED: To improve luminance while maintaining the operating voltage in an organic electroluminescent device. SOLUTION: This multilayer electroluminescent device is formed by including an anode, a hole transport layer (HTL), a light emitting layer (LEL), and is characterized in that an intermediate layer (IL) including a compound having 3-phenylindolyl group is disposed between the HTL and the LEL.
