METHOD AND APPARATUS FOR MANUFACTURING ORGANIC ELECTROLUMINESCENT ELEMENT, AND ORGANIC ELECTROLUMINESCENT MODULE

摘要

Disclosed is a method for manufacturing an organic EL element, which has, on a supporting substrate, at least one intermediate electrode layer, and at least two light emitting units, each of which has one or a plurality of organic functional layers, the intermediate electrode layer being disposed between the light emitting units. The method is characterized in having: a first patterning step wherein at least one organic functional layer of each of the light emitting units is patterned using a mask; and a second patterning step wherein at least one organic functional layer in each of the light emitting units is patterned into, by means of light irradiation, a region where a light emitting function is modulated, and a region where the light emitting function is not modulated. The method is also characterized in that the second patterning step is performed for each light emitting unit that is manufactured.

1. A method of producing an organic electroluminescent element comprising a support substrate having thereon: at least two light emitting units each containing one or a plurality of organic functional layers; and at least one intermediate electrode layer, the intermediate electrode layer being arranged between the light emitting units,
the method comprising: patterning with a mask at least one of the organic functional layers in each of the light emitting units; and patterning the at least one of the organic functional layers by light irradiation into a region where a light emitting function is modulated, and a region where a light emitting function is not modulated, wherein the patterning by light irradiation is conducted each time when each of the light emitting units is produced.
