This paper presented a study about how feasible the color filter (CF) of LCD can be manufactured by applying the inkjet print technology. In the study, it included the ”feasibility of CF ink” ”feasibility of CF head” ”feasibility of printing system” ”feasibility of industrial fabrication” and so on. In summary, although there may be much difficulty in those new development of technology, it is still very promising in the near future to Implement the inkjet printing to manufacture the product of color filter.
