DEFICIENCY CORRECTION METHOD OF HOLOGRAM COLOR FILTER

摘要

PROBLEM TO BE SOLVED: To provide a deficiency correction method in case scattering deficiency of a hologram color filter occurs or any factor hologram of a hologram color filter are not made as the design. SOLUTION: In the deficiency correction method, a hologram recording layer 11 consisting of a photopolymer is provided and a defective part D of the hologram recording layer 11 of a hologram color filter 5 stabilized in development by recording the array of a light-collecting hologram interference pattern being made eccentric in the hologram recording layer 11 is irradiated with a laser beam of a exposure photographic sensitivity wavelength region of the photopolymer by the light quantity density of 100 times or more of the hologram interference pattern exposure of the photopolymer so that the laser beam is made to denaturalize so as to decrease the light quantity of forward scattering from the defective part D.
