METHOD FOR MANUFACTURING AN LCD FOR SIMPLIFYING AN ALIGN KEY FORMATION PROCESS

摘要

PURPOSE: A method for manufacturing an LCD(Liquid Crystal Display) is provided to simplify an align key formation process needed in a cell process. CONSTITUTION: An ink jet printing device comprises an ink jet head(56). A vertical head driving member(54c) has a moving shaft(55) for moving the ink jet head to upper and lower portions of an upper substrate(50). Upper and lower head driving members(54a,54b) move the ink jet head, the moving shaft and the vertical head driving member toward right and left. When inputting a signal, the ink jet printing device drops ink to a dummy region(51) of the upper substrate(50), so that an align key(53) is formed.
