Color filter printing method, color filter printing apparatus, and color filter substrate
Abstract:
A gravure printing plate is arranged on a stage, and recessions formed in the gravure printing plate are filled with photosensitive ink. The ink fills the recessions by being placed on an end of the gravure printing plate and being wiped with a blade. The gravure printing plate is then heated while the gravure printing plate is irradiated with UV light from the bottom side of the stage, thereby curing the lower stratum of the ink in the recessions. A blanket is then pressed against the gravure printing plate, and rotated to accept the ink filling the recessions. The ink accepted onto the blanket is then transferred to a transparent substrate, effecting printing of the color filter. It is accordingly possible to print a color filter having a color filter layer with a highly accurate pattern configuration, without any contaminant matter being transferred to the color filter layer.
