Color conversion sheet and backlight unit comprising same

Abstract

A color conversion sheet according to an embodiment of the present invention comprises: a wavelength conversion layer in which an organic phosphor is dispersed in a resin matrix; and a light absorption layer in which an organic light absorber located on one side of the wavelength conversion layer is dispersed in a binder resin. Thus, the color conversion sheet uses environmentally safe organic phosphors by absorbing short-wavelength blue light that deteriorates organic phosphors without affecting the emission characteristics of the organic phosphors included in the wavelength conversion layer, has excellent color reproduction rate and luminance characteristics, undergoes little color change when irradiated with light and has excellent luminance reliability, not only at room temperature but also in high-temperature environments, and has excellent performance in terms of eye protection.
