Abstract
The column spacer and overcoat layer of the color filter substrate for liquid crystal displays formed at once by capillary force lithography was studied using UV-replica mold and UV-curable liquid resin. The low viscosity and rapid curing speed of the liquid resin make it possible to pattern successfully in the industry application. We can estimate the coating thickness in order to achieve desired overcoat thickness according to mass balance. The formed overcoat layer and column spacer exhibited both satisfied transmittance and recovery ratio for liquid crystal display as commercial these for photo-lithography method. Finally, we demonstrated the panel using this technique and material. This work can provide a possibility for simply and low-cost process to form a functional layer in display.
