Abstract

An apparatus for repairing a defect recognizes a defective portion of a color filter using an image processing mechanism, applies ink to the recognized defective portion of the color filter using a needle for applying ink of an ink application mechanism, hardens the applied ink using an ink hardening mechanism, and removes an unnecessary portion of the applied ink by irradiating laser beam from a laser irradiation mechanism.
