摘要： In an organic thin film (a light emitting layer) of an organic EL element, an organic thin film having an emitting material which is made up of an organic polymer main backbone polymerized with a molecular chain, which emits light having a maximum value at a wavelength different from a wavelength at which an emission spectrum emitted by the main backbone itself has a maximum value, and nanosized particles which are mixed into the emitting material is used as the light emitting layer. According to the above configuration, the maximum values of the emission spectra of light emitted by the molecular chain and the main backbone of the emitting material can be increased. Moreover, the light which has the emission spectra having the plural maximum values can be generated without depending on the plural emitting materials, so that the light emitting layer can be manufactured easily.
