Title
(EN) Composite material, material for light-emitting element, light-emitting element, light-emitting device and electronic device
Abstract
(EN)

The present invention provides a composite material for a light-emitting element including a high molecular compound having an arylamine skeleton and an inorganic compound showing an electron accepting property to the high molecular compound. The absorption spectrum of the composite material is different from absorption spectra of the high molecular compound and the inorganic compound which each form the composite material. In other words, a composite material having an absorption peak in a wavelength which is seen in the absorption spectra of neither the high molecular compound nor the inorganic compound forming the composite material is superior in carrier transporting and injecting properties and a favorable material. In addition, the composite material can be formed by a wet method such as a sol-gel method, it can be apply to the increase of substrate size easily in a manufacturing process and advantageous industrially.
