Organic device manufacturing method

A method for producing an organic device, comprising:

• a first forming step of forming an organic functional layer including at least a light emitting layer on a first electrode layer disposed on a substrate;
• and
• a second forming step of forming a second electrode layer on the organic functional layer,
• wherein an upper limit value of an integrated absorption irradiance of light in an environment until formation of the second electrode layer starts in the second forming step after formation of the light emitting layer starts in the first forming step is set and the organic functional layer is found so that the integrated absorption irradiance is the upper limit value or less,
• wherein the integrated absorption irradiance is an integrated value of integrated irradiances for wavelengths of the light of a material that forms the light emitting layer, and
• wherein the upper limit value of the integrated absorption irradiance at which a product lifespan is a predetermined time or longer is set on the basis of a relationship of the integrated absorption irradiance with relative lifespan and relative current luminous efficiency so that the product lifespan of the organic device set based on the relative lifespan and the relative current luminous efficiency caused by the integrated absorption irradiance is the predetermined time or longer.
