Abstract
A film for a backlight unit including a semiconductor nanocrystal-polymer composite film including a semiconductor nanocrystal and a matrix polymer in which the semiconductor nanocrystal is dispersed, wherein the matrix polymer is a polymer produced by a polymerization of a multifunctional photo-curable oligomer, a mono-functional photo-curable monomer, and a multifunctional photo-curable cross-linking agent, the multifunctional photo-curable oligomer has an acid value of less than or equal to about 0.1 mg of KOH/g, and a content (A1) of a first structural unit derived from the multifunctional photo-curable oligomer, a content (A2) of a second structural unit derived from the mono-functional photo-curable monomer, and a content (A3) of a third structural unit derived from the multifunctional photo-curable cross-linking agent satisfy Equation 1:A1<(A2+A3).
