<p>PURPOSE: A method for manufacturing a color filter, the color filter, a light emitting diode illuminating apparatus using the same are provided to obtain warm white light while the maximum power efficiency is maintained. CONSTITUTION: A photopolymerizable composition includes a photopolymerizable initiator and a urethane acrylate oligomer. The photopolymerizable composition is hardened by radiating ultraviolet ray with the dose of 500 to 5000mf/cm^2. The hardened photopolymerizable composition is thermally processed. The urethane acrylate oligomer includes a urethane bond and 2 to 12 acrylic functional groups.</p> |
