Abstract
The device of manufacturing a color filter relating to the invention is provided with a laser irradiation device, in which the condensing lenses are spaced with a pitch whereby a color pattern of the same color of R, G, B can be formed, and are disposed so as to shift positions toward a scanning direction. Further, the laser generation unit of the laser irradiation device has coils made by the optical fibers being curled on the paths, which expand the wavelength band near the center of the laser beams, thus unifying the energy intensity of the part where the laser beams are irradiated. Further, the head unit of the laser irradiation device is provided with cooling means to control the temperature in the head, which prevents displacements in the arrangement pitches of the optical fibers.
