Claim 0:
1. 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 matrix comprising a polymer, and a plurality of cadmium-free quantum dots dispersed in the matrix,
wherein the quantum dot-polymer composite has a light absorption rate of greater than or equal to about 89% at wavelength of 450 nanometers,
wherein the quantum dot-polymer composite further comprises metal oxide fine particles dispersed in the 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.
