<p>PROBLEM TO BE SOLVED: To provide a liquid crystal display device in which short-circuiting and separation of data and gate short-circuit lines are made possible, and to provide a gate short-circuit bar and its manufacturing method. SOLUTION: The device has the following structure, i.e. when it is to form a gate short-circuit line and a data short-circuit line 131, the upper layer Mo metal of each short-circuit line includes a neck shaped Mo-bridge 100 having a width of 3.5 to 4.5μm and a length that is equal to or less than severalμm. In the bridge 100, a tilted surface that makes a boundary between the bridge and an adjacent portion having a different width with respect to the bridge has a tilt angle between 20 to 70 degrees and the tilt angle of the tilted surface which opposes the tilted surface is set between 110 to 160 degrees. The distance in which the Al metal of the lower layer having a neck shaped Mo bridge is set to severalμm to several tens ofμm so that each short-circuit line stably maintains short-circuiting.</p> |
