摘要： The present invention is to provide a method of favorably forming an organic EL device with the inverted structure by the wet process. On that account, an organic EL device includes a cathode, an electron injection layer, a light emitting layer, a hole transport layer, a hole injection layer, an anode are formed in this order on a substrate. The electron injection layer is formed by applying ink between banks and drying the ink. The ink is formed by dissolving a polymer compound having an organic phosphine oxide skeleton in an alcohol solvent. The light emitting layer is formed by applying ink between components of the bank and the drying the ink. The ink is formed by dissolving material for light emitting layer such as polyphenylene vinylene (PPV) derivative or polyfluorene derivative in a nonpolar solvent.
