  • Ink composition and method of fabricating liquid crystal display device using the same
    Patent number: 7935552
    Abstract: Disclosed are an ink composition and a method for fabricating a liquid crystal display (LCD) device using the same, wherein in forming patterns of the LCD device using an imprint lithography and a roll printing, an ink composition with high thermal resistance, consisting of polymer resin and additive both endurable even at a high temperature is used to form fine patterns with constantly maintaining pattern linewidths and line intervals, the ink composition consisting of 5-45% by weight of polymer resin, 5-45% by weight of additive added to retain thermal stability, and 50-90% by weight of organic solvent, wherein the ink composition is endurable even at a high temperature of 90-250° C.
