Wavelength conversion member, backlight unit including the same, liquid crystal display device, and method for manufacturing wavelength conversion member

摘要

Provided is a wavelength conversion member including: a wavelength conversion layer including at least one kind of quantum dots that are excited by excitation light to emit fluorescence and are dispersed in an organic matrix; an intermediate layer that is provided adjacent to at least one main surface of the wavelength conversion layer; and a barrier layer that is provided adjacent to a main surface of the intermediate layer opposite to the wavelength conversion layer and includes silicon nitride and/or silicon oxynitride as a major component, in which the organic matrix is obtained by curing a curable composition including at least an alicyclic epoxy compound, and the intermediate layer includes a chemical structure A which is bonded to silicon nitride and/or silicon oxynitride as a major component of the barrier layer and a chemical structure B which is bonded to the organic matrix.
