Title:
AMINE COMPOUND AND ORGANIC ELECTROLUMINESCENT ELEMENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/074767
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a compound which absorbs light having a wavelength of 400 nm to 410 nm from sunlight, does not affect a material inside an organic EL element, and has a high refractive index in a wavelength range of 450 nm to 750 nm, in order to prevent deterioration inside the organic EL element and to significantly improve the light extraction efficiency of the organic EL element. The present invention provides an amine compound which has a specific benzazole ring structure with a high refractive index. An organic EL element having a high light emission efficiency can be achieved by using the compound according to the present invention as a constituent material for a capping layer.
