Claim:
1. A backlight unit for a liquid crystal display device, the backlight unit comprising: a light emitting diode light source; a light conversion layer disposed separate from the light emitting diode light source to convert light emitted from the light emitting diode light source to white light and to provide the white light to a liquid crystal panel; and a light guide panel disposed between the light emitting diode light source and the light conversion layer, wherein the light conversion layer comprises a polymer matrix and a semiconductor nanocrystal dispersed in the polymer matrix, and wherein the polymer matrix comprises a first polymerized product of monomers selected from the group consisting of wherein, in Chemical Formula 2, X is a C2 to C30 aliphatic hydrocarbon group including a carbon-carbon double bond or a carbon-carbon triple bond, a C6 to C30 aromatic hydrocarbon group including a carbon-carbon double bond or a carbon-carbon triple bond, or a C3 to C30 alicyclic hydrocarbon group including a carbon-carbon double bond or a carbon-carbon triple bond, R L Y n is an integer of 1 or more, k3 is an integer of 0 or 1 or more, k4 is an integer of 1 or more, the sum of n and k4 is an integer of 3 or more, n does not exceed the valance of Y the sum of k3 and k4 does not exceed the valence of the L wherein the at least one second monomer is not silane or siloxane, and wherein neither the at least one first monomer nor the at least one second monomer is substituted with an acid group.
