Abstract
A wavelength conversion member, is provided with a wavelength conversion layer that includes quantum dots and is interposed between two barrier layers. The wavelength conversion member includes a light scattering layer that is provided between the barrier layers and the wavelength conversion layer, in which one of the barrier layers closest to the light scattering layer is formed of an inorganic component, the light scattering layer includes a binder, which is formed of either a compound having a hydrogen bonding functional group and a polymerizable group in a molecule or an organic metal coupling agent, and scattering particles having a diameter R of 0.2 to 5 μm, a thickness d of the light scattering layer is 0.2 to 4 μm, a thickness D of the wavelength conversion layer is 10 to 100 μm, and a ratio of d to D is 0.2% to 10%.
