摘要

A polymer a luminescent material, and the likes are provided, wherein a film can be formed by a wet film-forming method, the film formed has a high stability, and is capable of being laminated with other layers by a wet film-forming method or another method, which are less decrease in charge transportation efficiency or luminescent efficiency, and attain an excellent driving stability. The polymer has a thermally dissociable and soluble group.
