Abstract: In the display device according to an embodiment, optical functional elements such as a prism sheet and a light diffusion layer are combined, and an optical composite sheet to which a light absorbing layer that selectively absorbs light of a specific wavelength band is inserted is used, so that the color gamut can be enhanced as compared with the prior art.

Abstract: An optical composite sheet is disclosed. In the optical composite sheet, optical functional elements such as a prism sheet and a light diffusion layer are combined, and a light absorbing layer that selectively absorbs light of a specific wavelength band is inserted, so that the optical performance and color gamut can be enhanced as compared with the prior art. In particular, the color transmittance of the optical composite sheet with respect to wavelength measured for each viewing angle satisfies a specific relationship, whereby it is possible to effectively reduce the color deviation with respect to the viewing angle.

Abstract: In the optical sheet according to an embodiment, at least one organic dye that selectively absorbs light in a specific wavelength band is added to a prism pattern layer, whereby it is possible to provide an optical sheet by a simpler manufacturing process than before, in which the color gamut is enhanced while a decrease in luminance due to light absorption is minimized. In addition, it is possible to secure optical and mechanical properties while preventing a degradation of organic dyes due to UV curing by adjusting the composition of the prism pattern layer.
