Abstract
Disclosed are an ink composition including light-absorbing nanoparticles and a photonic crystal structure formed using the same. The ink composition may include inorganic particles; monomer; photoinitiator; and nanoparticles light-absorbing nanoparticles to provide the photonic crystal structure. As consequence, problems such as low color sharpness, which makes photonic crystals visible, and attaining high productivity may be eliminated. Moreover, white scattering can be reduced, and thus a distinctive color can be exhibited even when there is a difference between a reflection angle and an observation angle of light, thereby improving visibility.
