description In order to prevent deterioration inside an organic EL element and significantly improve the light extraction efficiency, an object of the present invention is to provide a compound that absorbs light rays with wavelengths of 400 to 410 nm of sunlight, thereby preventing them from affecting a material inside the element, and has a high refractive index in a wavelength range of 450 to 750 nm. The present invention provides an amine compound having a specific benzazole ring structure having a high refractive index. An organic EL element having excellent light emission efficiency is obtained by using the compound of the present invention as a material constituting a capping layer.
