Abstract

A wiring structure of a wiring area on a liquid crystal displaying panel includes a number of wiring lines connected to one end of a corresponding data line and corresponding scan line on the wiring area, at least one signal testing point, a number of first testing lines connected between the wiring lines and the signal testing point, a number of second testing lines connected between the signal testing point and the other end of the corresponding data line and the corresponding scan line, and a switch controlling circuit connected to the second testing lines. After the testing lines are disconnected from the wiring lines in the previous process, the testing signal still can be transmitted through the other end of the corresponding data line or the scan line, to implement the image test of the liquid crystal displaying panel.
