ABSTRACT:
A method for manufacturing a bottom substrate of a liquid crystal display device is disclosed. The method is achieved by proceeding two lithography processes cycles with a single mask. Therefore, the method of the present invention can manufacture a bottom substrate through five lithography processes cycles with only four masks. Thus, the cost of a liquid crystal display device can be reduced due to the absence of the manufacturing cost of one mask.
