Patent ID: 7935544

Claim:
A method of manufacturing an organic light-emitting device, comprising the steps of: forming, over a drive substrate, an element region including a drive transistor, and an organic electroluminescence element in which, an anode, an organic layer and a cathode are stacked in this order; after forming the element region, forming a protection film on the cathode; after forming the protection film, repairing a short circuit area in which the anode contacts the cathode by applying a voltage across the anode and the cathode while simultaneously subjecting at least the element region, when the voltage is applied, in an atmosphere in which an oxygen concentration by volume is 0.1% or higher and less than 1% and a dew point temperature is −50 degrees or less, and completing the manufacture of the organic light-emitting device, said repairing step occurring prior to the completion of the organic light-emitting device, wherein, the protection film is formed to have a thickness such that a part of the cathode within the short circuit area is not covered by the protection film, the voltage applied across the anode and the cathode in repairing is of an alternating application method of alternately applying a forward-direction potential and an inverse-direction potential, and the difference between the forward-direction potential and the inverse-direction potential applied to the organic electroluminescence element is set to 30V or higher, and equal to or lower than an initial withstand voltage of the drive transistor.
