The present invention relates to a colloidal dispersion composition comprising light absorbing nanoparticles and to a photonic crystal structure formed therefrom and, more specifically, to a photonic crystal structure which improves low color sharpness, a problem in which photonic crystals are visible by injecting the light absorbing nanoparticles into a photopolymerizable colloidal dispersion, and maintains high productivity. In addition, the visibility can be improved by allowing a clear color to appear even if there is a difference in the reflection angle and the observation angle of the light caused by reducing white scattering.
