Provided is an apparatus and method of manufacturing a color filter adsorbing toner nano-particles by using electrostatic force. In the apparatus for manufacturing the color filter, a laser driver generates at least one laser control signal according to electrification data, at least one laser device forming a laser irradiation unit which irradiates a laser for a predetermined time according to the at least one laser control signal. According to the irradiated laser, electrostatic latent images are formed in positions of color filter cells having a predetermined resolution standard requirements in a glass substrate, and toner nano-particles are electrostatically adsorbed to the formed electrostatic latent images.
