Estimating the term…
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.
A quantum dot-containing resin sheet or film comprising a stack of a plurality of resin layers, at least one of the resin layers containing quantum dots,
A quantum dot-containing resin sheet or film comprising resin layers containing two or more types of quantum dots with different fluorescence wavelengths, each of the two or more types of quantum dots having a different concentration gradient in a thickness direction of the resin layers.
