PROBLEM TO BE SOLVED: To provide a plurality of organic electroluminescent elements each having uniform element performance in a case where a plurality of the elements each having the same configuration are manufactured in series.SOLUTION: An organic electroluminescent element has a pair of electrodes comprised of an anode and a cathode and an organic layer including a luminous layer between the electrodes on a substrate. The luminous layer has a platinum complex having a specific structure and a host material; a difference between the emission maximum wavelength λ1 when the element is electrically energized and the emission maximum wavelength λ2 when the platinum complex having the specific structure is dissolved in dichloromethane at a concentration of 5 mg/L to be photoexcited is 3 nm or less. |
