Abstract
According to the present disclosure, a method for producing an optoelectronic component is provided. The method includes forming an organic first layer above a substrate, and forming an organic second layer above the first surface region. The first layer includes a surface. The surface is opposite the substrate and includes a first surface region and a second surface region. The second surface region surrounds the first surface region. The second surface region remains free of the second layer . The first layer and the second layer differ in their chemical composition.
