PROBLEM TO BE SOLVED: To suppress generated leakage current in advance, caused by heat of the sealing process. SOLUTION: In the manufacturing method of the organic EL device, a photo- annealing is made before sealing, by making a light of irradiation wavelength λin a range 300-500 nm irradiated on the transparent insulating substrate 1 that is formed with the element main parts made of an anode 2, a positive hole transport layer 3, an organic luminous layer 4 and a cathode 5. |
