Patent ID: 8669024

Claim:
A method of fabricating a color filter substrate, comprising: coating a first color resist layer on an entire surface of a substrate; exposing the substrate; developing the exposed first color resist layer to form a first color filter pattern; coating a second color resist layer over the entire surface of the substrate; exposing the substrate; developing the exposed second color resist layer to form a second color filter pattern; partially curing the second color filter pattern by irradiating the substrate with infrared rays during an intermediate heating time; coating a third color resist layer over the entire surface of the substrate; exposing the substrate; developing the exposed third color resist layer to form a third color filter pattern; and simultaneously curing the first to the third color filter patterns by irradiating the substrate with infrared rays during a final heating time, wherein the intermediate heating time is decided within a range in which a shape of the first and second color filter patterns can be maintained in a subsequent development process, and wherein a coating sequence is selected according to a difference in a development characteristic of each of the first to third color resist layers such that a material for the first color resist layer is selected to maintain a pattern characteristic without a curing process, a material for the second color resist layer is selected to maintain a pattern characteristic with a partial infrared curing process, and a material for the third color resist layer is selected to have a pattern characteristic with complete infrared curing process.
