Method for producing an organic electroluminescence display element

摘要

A method for producing an organic EL display element is presented to improve the emission luminance lifetime and to stabilize emission characteristics. In a method for producing an organic electroluminescence display element having a light emitting layer between an anode and a cathode, 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 are carried out in combination, 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.
