Abstract
A method for producing an organic EL device having an anode, a cathode, at least one organic functional layer disposed between the anode and the cathode, and a sealing layer, comprising a step of forming the anode, a step of forming the cathode, a step of forming the at least one organic functional layer and a step of forming the sealing layer, wherein the average concentration: A (ppm) of a nitrogen oxide to which the organic EL device during production is exposed from initiation time of the step of forming the at least one organic functional layer until termination time of the step of forming the sealing layer and the exposure time thereof: B (sec) satisfy the formula (1-1): 0≤A×B<12 (1-1).
Claims10
A method for producing an organic EL device having an anode, a cathode, at least one organic functional layer disposed between the anode and the cathode, and a sealing layer, comprising
- a step of forming the anode, a step of forming the cathode, a step of forming the at least one organic functional layer and a step of forming the sealing layer,
- wherein the average concentration:
