Abstract
To provide a quantum dot-containing resin sheet or film, a method for producing the same, and a wavelength conversion member that can, in particular, solve the problem of aggregation of the quantum dots and the problem with the use of a scattering agent, suppress a decrease in light conversion efficiency, and improve the light conversion efficiency of a resin molded product containing quantum dots. The quantum dot-containing resin sheet or film of the present invention includes a stack of a plurality of resin layers, at least one of the resin layers containing quantum dots, and the plurality of resin layers is integrally molded through co-extrusion.
