A pixel structure is provided. The pixel structure comprises a scan line,
a data line, a pixel electrode and a thin film transistor. The data line
branches out into a plurality of subsidiary lines in the area above the
scan line. If there is a short circuit between the scan line and the data
line, the short circuit can be repaired by cutting the connections to one
of the branching subsidiary lines. In one embodiment of this invention, a
repair line is set up on one side of the data line such that a portion of
the repair line crosses over the scan line. If there is a short circuit
between the scan line and the data line, a laser repair operation can be
carried out through the repair line.
