Method of manufacturing color filters and liquid crystal display device using these color filters

After forming a black matrix which defines pixel regions on a substrate, dyed substrate layers of photo hardening property are formed. By irradiating ultraviolet rays to the dyed substrate layers from the back of the substrate and by developing, ink reservoirs which use the black matrix as partition walls are formed. The dyeing material such as the dye is supplied to these ink reservoirs by an ink jet system. Due to these partition walls, there is no possibility that the dyeing material scatters to the neighboring or adjacent pixel regions to cause the mixed color. Further, since the filters having a sufficient thickness can be formed in the ink reservoirs, the surface flatness of the color filters can be sufficiently ensured without coating the thick overcoat layer.

The technique is the improvement of the traditional BAF technique, removes the resolvable organism in the sewage through the biological degradation, outtakes the water into the air-bearing system and combines the flocculation medicine adding technique, so as to eliminate the non-solvent organism and colloidal substance in the sewage. The outtaken water enters into the ozone contact oxidation tower and gets mixed with ozone, so that the organism which is difficult to undergo the biological degradation in the printing and dyeing sewage is removed with the help of the strong oxidizing property of the ozone. The water flowing out of the ozone contact oxidation tower enters into the pond at the middle, and 30 percent of the water returns to a gas dissolving can under the action of a pressurizing pump, gets mixed with the pressurized air and then enters into the air-bearing system through utilizing the remaining pressure. The gas-water solution is dispersed into the small and equable drips through a dissolved gas releaser, and the drips drive the suspending substances and the colloidal substance to float up to the water surface so as to achieve the removal. The water coming out of the middle pond enters into the filter to remove the small suspending substances and enters into the ozone / active carbon filtering system so that the reaction of the ozone basic chain is caused under the action of the active carbon, thereby speeding up the decomposition of the ozone into OH and other free radicals, degrades a small amount of organism, eliminates the color and finally ensures that the outtaken water reaches the recovery standard of the printing and dyeing sewage.
