Beschreibung
Zusammenfassung:	An optical composite sheet according to an embodiment of the invention comprises a reflective polarizing film in which a first resin layer and a second resin layer having different optical properties from each other are alternately laminated in 100 to 2,000 layers, a prism sheet disposed under the reflective polarizing film, a light diffusion layer disposed under the prism sheet, and a light absorbing layer disposed on one side of any one of the reflective polarizing film, the prism sheet, and the light diffusion layer and selectively absorbing light of a specific wavelength band. In the optical composite sheet according to an embodiment of the invention, 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, it is possible to minimize the decrease in luminance due to the absorption of light by the light absorbing layer while enhancing the color gamut by adjusting the lamination configuration of the optical composite sheet.
