Abstract

In a method for producing an organic light emitting illuminant, a base electrode layer is formed over a substrate, an organic light emitting layer is formed over at least one portion of the base electrode layer, and a top electrode layer is formed over at least one portion of the organic light emitting layer, the layers being formed in the shape of strips. The strip-shaped formation of the layers is carried out in a coating process in an in-line vacuum coating system having stationary shadowing masks on the advancing substrate such that at least one area of the base electrode layer remains uncoated once the layers have been formed.
