  • Patent number: 8669024
    Abstract: A method of fabricating a color filter substrate and an infrared heating apparatus for the same are provided. A post-baking process is replaced with an infrared irradiation method with a rapid thermal transfer characteristic. Therefore, the yield and production efficiency can be improved. The method of fabricating a color filter substrate includes coating a color resist layer on an entire surface of a substrate, placing a mask on the substrate and exposing the substrate, developing the exposed color resist layer to form a color filter pattern, and curing the color filter pattern by irradiating the substrate with infrared rays.
