US 6,212,317 B1 · Method of manufacturing color filter and device of manufacturing the same

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.

Dependent claims

A device of manufacturing a color filter, in which, in a state that a color film sheet having a color ink layer of a specific color of a plurality of colors is disposed on a color transfer support, laser beams for melting the color ink layer are irradiated to the color film sheet, the device comprising:

condensing lenses for irradiating laser beams that are spaced with a pitch whereby a color pattern of the specific color of a plurality of the colors can be formed, and are disposed so as to shift positions toward a scanning direction, and a plurality of optical fibers disposed to face the condensing lenses are mounted on a head;
and
optical paths of the laser beams generated from a plurality of laser oscillators are connected optically individually to the optical fibers mounted on the head.
