  • Patent number: 6987548
    Abstract: A liquid crystal display (LCD) device and method for manufacturing the same in which a plurality of patterns are formed on one substrate reduces the manufacturing cost and simplifies the process steps by minimizing the number of masks required to form the patterns. The LCD device includes first and second substrates, a thin film transistor (TFT) formed in a predetermined region on the first substrate, a pixel electrode formed in a pixel region on the first substrate, a color filter layer formed on the pixel electrode, a black matrix pattern formed in a region other than the pixel electrode, and a liquid crystal layer formed between the first and second substrates. The method for manufacturing the LCD device having a pixel region defined by gate and data lines, includes the steps of forming a TFT on a first substrate, forming a black matrix pattern in a region other than the pixel region, forming a pixel electrode in the pixel region, and forming a color filter layer on the pixel electrode.

  • Patent number: 6853405
    Abstract: There is disclosed a method of fabricating a liquid crystal display that is adaptive for increasing the capacitance of a storage capacitor. A method of fabricating a liquid crystal display according to an embodiment of the present invention includes forming a thin film transistor at an area where a gate line crosses a data line; forming a protective film to cover a substrate where the thin film transistor is formed; simultaneously forming a perforation hole and a contact hole by selectively eliminating the protective film using a partial exposure mask; and forming a pixel electrode contacting a gate insulating film and a drain electrode of the thin film transistor through the perforation hole and the contact hole respectively.

  • Patent number: 6630976
    Abstract: A TFT array substrate for use in an LCD device includes at least one repair line to repair line defects. The repair line(s) is formed when forming the pixel electrode so that additional process steps are not required. Accordingly, productivity can be increased. Moreover, either a short-circuit or an open-circuit can be repaired due to the repair line(s).
