  • Publication number: 20040196416
    Abstract: A fabrication method of a liquid crystal display device uses a printing method which forms a pattern of a wider effective line width such as a gate line, a data line, a passivation layer, a pixel electrode, etc. constituting an LCD device. The inventive lithography process uses a mask that is applied at the time of forming a channel region having a narrow effective line width. Accordingly, the amount of resist used may be reduced, and the fabrication process can be simplified. This printing method can be used to fabricate a color filter substrate of an LCD device.
