LIQUID CRYSTAL DISPLAY DEVICE, ITS PRODUCTION AND DETECTING METHOD OF DEFECT

摘要

PROBLEM TO BE SOLVED: To provide a thin film transistor substrate having short bars which make detection of short circuit fault easy and which are not damaged by electrostatic charges by arranging plural first wirings parallel to one another, plural second wirings formed parallel to the first wirings, first and second short bars connected to the first and second wirings, and main short bars formed outside the first and second short bars. SOLUTION: First and second auxiliary short bars 410, 420 are formed between a gate short bar 200 and gate pads 110, 120 and parallel to the gate short bar 200. Third to fifth subshort bars 210, 220, 230 are formed between a data short bar 400 and data pads 510, 520 and parallel to the data short bar 400. In this structure. the first and second auxiliary short bars 410, 420 are connected to G1, G3, and G2, G4, respectively. The third to fifth auxiliary short bars 210, 220, 230 are connected to data lines D1 and D4, D2, D3, respectively.
