Apparatus and method of fabricating alignment layer for liquid crystal display using a nano pattern mold

A method for fabricating an alignment layer for a liquid crystal display comprising:

• coating an alignment agent on a substrate;
• arranging a nano pattern mold with a groove and a protrusion to contact the alignment agent;
• pre-curing the alignment agent in contact with the nano pattern mold on a hot plate in the form of a conveyor belt;
• separating the nano pattern mold from the alignment agent to reverse transcribe the groove and protrusion of the nano pattern mold into the alignment agent into a reverse transcribed pattern;
• after separating the nano pattern mold from the alignment agent, conveying the substrate from the hot plate on the conveyor belt to a hard-curing apparatus in an in-line manner;
• hard-curing the alignment agent separated from the nano pattern mold to form an alignment layer to maintain the reverse transcribed pattern after separating the nano pattern mold from the alignment agent;
• and
• aligning liquid crystal in a longitudinal direction of the groove of a nano pattern of the alignment layer,
• wherein the step of pre-curing comprises:
• allowing the nano pattern mold and the alignment agent to be kept at ambient temperature and pressure for 1 to 20 minutes, while the nano pattern mold contacts the alignment agent;
• and
• pre-curing the alignment agent in contact with the nano pattern mold at a temperature of 100° to 120° for 1 to 20 minutes.
