ABSTRACT:
The present invention reduces overall electrostatic capacity by effectively reducing capacitor surface area. In one embodiment, each data line is formed so that it directly intersects or overlaps a repair line that surrounds the LCD screen a single time at an end of the data line corresponding to a data line input pad. The other end of the data line does not intersect with the repair line, but instead uses a conductive layer that overlaps this other end of the data line at one end and the repair line at another end. In another embodiment, a plurality of repair lines that each surround the LCD screen are used. Groups of data lines are associated with one repair line and the widths of the data lines are narrowed if the data line intersects a repair line that it is not associated with. Accordingly, by preventing one end of a data line from intersecting with a repair line, or by reducing the width of data lines which cross a non-associated repair line when a plurality of repair lines are used, the overall electrostatic capacity is reduced.
