LIGHT CONVERSION FILM INCLUDING QUANTUM DOT LAYER, BACKLIGHT UNIT FOR DISPLAY DEVICE INCLUDING LIGHT CONVERSION FILM, AND METHOD FOR MANUFACTURING QUANTUM DOT DISPERSION SOLUTION

摘要

The present invention provides a light conversion film which includes a first transparent support layer formed on an upper surface of a quantum dot layer and a second transparent support layer formed on a lower surface thereof and has a thickness 120 to 400 m, a backlight unit for a display device including the light conversion film, a display device, a composition for forming a quantum dot layer, and a method for manufacturing a particle dispersion solution. The quantum dot layer comprises, with respect to 100 wt% of the quantum dot layer, 0.4 to 2.0 wt% of quantum dot particles containing 5 or more to less than 35 wt% of cadmium; 0.05 to 0.75 wt% of cadmium-free quantum dot particles; 0.1 to 10 wt% of a scattering agent; and 75 to 98 wt% of a matrix material. The film has a cadmium content of 10 to 100 ppm. Therefore, the light conversion film can exhibit excellent luminance and color reproduction characteristics.;COPYRIGHT KIPO 2020
