A novel ink jet printing process without additional photolithography process for large area color filter fabrication has been developed in this study. A 100x100 mm(2) model of 32" color filters was fabricated for evaluation. New developed RGB inks were able to achieve 73% NTSC standard with the thickness of R, G, and B films at 1.80, 1.90, and 1.80 pm, respectively. The overflow issue can be solved by surface pretreatments, and color inks formulation.

A 4 "color filter panel was successfully prepared by rib-less ink jet printing process. The smeared ink issue can be controlled by surface treatment on both Cr and glass with similar contact angle. The color line formation can be prepared by either two-step printing process at room temperature or one-step printing at elevated temperature. The thickness of red, green and blue films were about 1.2 mu m, 1.0 mu m and 1.0 mu m, respectively. The panel's NTSC value was estimated at 53.5 +/- 0.7%.
