Claim 14:
15. A quantum dot-polymer composite pattern, comprising
a section configured to emit light of a predetermined wavelength,
wherein the quantum dot-polymer composite comprises a polymer matrix comprising a polymer, and a plurality of cadmium-free quantum dots dispersed in the polymer matrix,
wherein the quantum dot-polymer composite has a luminous efficiency of greater than or equal to about 33%,
wherein the quantum dot-polymer composite further comprises metal oxide fine particles dispersed in the polymer matrix, and
wherein in the quantum dot-polymer composite, an amount of the quantum dots is greater than or equal to about 40 weight percent and less than or equal to about 80 weight percent, and an amount of the metal oxide fine particles is greater than or equal to about 4 weight percent and less than or equal to about 25 weight percent, based on a total weight of the quantum dot-polymer composite.
