Abstract
An auxiliary wire, which can be connected to each of a plurality of data signal lines (Sn), is constituted by (i) a first auxiliary wire (17) provided so as to intersect the plurality of data signal lines (Sn) on a side where end parts of the respective plurality of data signal lines (Sn) are connected to a data signal line driving circuit (4) and (ii) a second auxiliary wire (18) provided so as to intersect the plurality of data signal lines (Sn) on a side of the other end parts of the respective plurality of data signal lines (Sn). Between the first auxiliary wire (17) and the second auxiliary wire (17), there are provided (i) a positive-polarity amplifier circuit (6) for receiving a positive data signal from the data signal line driving circuit (4) and (ii) a negative-polarity amplifier circuit (7) for receiving a negative data signal from the data signal line driving circuit (4). An output signal is supplied to the second auxiliary wire (18) from the positive-polarity amplifier circuit (6) or the negative-polarity amplifier circuit (7).
