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.
