Abstract:
1. A method for producing an organic electroluminescence display element having a light emitting layer between an anode and a cathode, wherein: operations are carried out in the combination of aging in a forward direction wherein a voltage is applied to the light emitting layer under the condition that the potential of the anode is higher than the potential of the cathode and aging in a reverse direction wherein a voltage is applied to the light emitting layer under the condition that the potential of the cathode is higher than the potential of the anode, and the integration value with respect to an applied voltage and a voltage application time in the aging in a reverse direction is at least twice as much as the integration value with respect to an applied voltage and a voltage application time in the aging in a forward direction over the entire aging process.
