Title: INK COMPOSITION FOR ORGANIC SEMICONDUCTOR ELEMENTS, AND ORGANIC SEMICONDUCTOR ELEMENT USING SAME
Abstract:
A layer, formed with a coating film having a leveling agent oriented on the surface thereof, has the leveling agent oriented on the surface portion. It has been found that, in such a case, the surface of such a layer has a reduced level of surface energy because of the presence of the leveling agent, and that, as a result, it is impossible or very difficult to form a layer on the layer formed using a leveling agent by a wet film-forming method. The purpose of the present invention is to provide an ink composition for organic semiconductor elements, which allows for the formation of a suitable film even on a layer having low surface energy. The present invention is an ink composition for organic semiconductor elements, which contains a first organic semiconductor element material, a leveling agent, a first solvent, and an aromatic solvent, wherein the leveling agent is a polymer that contains at least a siloxane monomer as a monomer unit, and the first solvent has a surface tension not higher than 25 mN/m.
