摘要：
One feature of the present invention is to provide a buffer layer made of a composite material for a light emitting element including aromatic hydrocarbon containing at least one vinyl skeleton and metal oxide in part of a light emitting substance containing layer, in the light emitting element formed by interposing the light emitting substance containing layer between a pair of electrodes. The composite material for a light emitting element for forming the buffer layer of the present invention has high conductivity and is superior in transparency.
