Liquid crystal display and fabricating method thereof

1. A liquid crystal display device comprising:

at least one signal line disposed in a display area and extending to a non-display area located outside the display area;

a common line crossing the signal line in the non-display area;

at least one static electricity preventing element connected between the common line and the signal line in the non-display area; and

at least one static electricity preventing auxiliary electrode projected towards the signal line from the static electricity preventing element in the non-display area,

wherein the static electricity preventing element comprises:

a first transistor including a source electrode and a gate electrode connected to the signal line in the non-display area;

a second transistor including a gate electrode connected to a drain electrode of the first transistor, and a source electrode connected to the signal line in the non-display area; and

a third transistor including a gate electrode connected to a drain electrode of the second transistor, a source electrode connected to the drain electrode of the first transistor, and a drain electrode connected to the common line, and

wherein the static electricity preventing element comprises a connecting electrode connecting the common line and the drain electrode of the third transistor,

wherein the static electricity preventing auxiliary electrode is projected towards the data line or gate line from the connecting electrode.
