<p>PROBLEM TO BE SOLVED: To provide a TFT array substrate having holding capacitance electrodes of a common wiring system which obviates the occurrence of the degradation in a yield by interlayer shorting, disconnection, etc., arising from process causes. SOLUTION: This TFT array substrate is provided with holding capacitance electrode lines 8 in proximity and holding capacitance electrode redundancy lines 9 having junctures for each of respective pixels in parallel with the holding capacitance electrodes lines 8 which are common lines. Even if the parts before and behind the part where the interlayer shorting arise are isolated by cutting with laser repair, etc., in the case of the occurrence of the shorting in the holding capacitance electrode lines 8 by foreign matter, etc., the holding capacitance electrode lines 8 are capable of maintaining the electrical connection by bypassing the holding capacitance electrode redundancy lines 9 from the juncture before and behind such part. Even if the holding capacitance electrode lines 8 are disconnected, the electrical connection is maintained by bypassing the holding capacitance electrode redundancy lines 9 from the juncture before and behind the disconnected part.</p> |
