Patent ID: 8012652

Claim:
A method of fabricating a LCD device, comprising: preparing a thin film transistor substrate and a color filter substrate, wherein the preparing at least one of the thin film transistor substrate and the color filter substrate includes the steps of: providing a printing roller; coating the printing roller with an etch-resist solution including a base polymer, a carrier solvent, a tackifier and a surfactant; removing the carrier solvent from the coated etch-resist solution thereby transitioning the etch-resist solution from liquid phase to solid phase; patterning the solid etch-resist; transferring the patterned etch-resist from the printing roller to the substrate; and patterning a thin film of the substrate corresponding to the transferred etch-resist; and providing a liquid crystal layer between the thin film transistor substrate and color filter substrate; bonding the thin film transistor substrate and the color filter substrate; and wherein the tackifier is used polyhydroxystyrene (PHS) having a plurality of hydroxyl (OH − ) groups and the PHS is combined with a hydroxyl group of the base polymer to form a hydrogen bond.
