ABSTRACT:
A method for forming a pattern of a liquid crystal display device is provided. The method includes providing a substrate having a layer to be patterned, providing a master substrate having an intaglio portion corresponding to a desired pattern, filling an organic material into the intaglio portion of the master substrate, placing the master substrate in contact with the substrate, hardening the organic material to produce a hardened organic film pattern, transferring the hardened organic film pattern onto a surface of the layer to be patterned by separating the master substrate from the substrate, and etching the layer to be patterned by using the organic film pattern as a mask.
