マイクロ毛細管チャネルを用いた平滑表面を有するカラーフィルタパターン作製プロセス

抄録

This paper proposes a patterning method for color filters using a method to introduce fluids of uncured color inks into capillaries with rectangular cross sections. Flat surface of color filter patterns can be obtained owing to the flat ness of top and bottom surfaces of the PDMS mold replicated from SU-8 photoresist patterns. In addition, the plural color filter patterns can automatically be formed by filling inks with capillary force. Mixing ratio of additive and solvent (dye, heptane, PVA and PDMS) were varied in order to decrease capillary filling time in consideration of capillary theory for viscous fluid.
