Abstract:
1. A liquid crystal display device comprising: a pixel array including a plurality of scanning lines arranged in rows, a plurality of signal lines arranged in columns, a plurality of liquid crystal elements arranged in a matrix corresponding to an intersection of each scanning line and each signal line, and a plurality of common connection lines arranged one by one corresponding to the liquid crystal elements of each line, the plurality of common connection lines including one or a plurality of first common connection lines and a plurality of second common connection lines; a scanning line drive circuit configured to sequentially apply a selection pulse to the plurality of scanning lines, and sequentially select the plurality of liquid crystal elements in a unit of the scanning line; a signal line drive circuit configured to apply a signal potential V a switching element arranged to correspond to each of the common connection lines, the switching element having (i) a first output terminal configured to switch a connection between each of the common connection lines and an auxiliary pulse generating device, and (ii) a second output terminal configured to switch a connection between each of the common connection lines and a logic circuit; and a common connection line drive circuit configured to (i) connect the one or the plurality of the first common connection lines to the auxiliary pulse generating device by the first output terminal, (ii) connect the plurality of second common connection lines to the logic circuit by the second output terminal, (iii) electrically separate the one or the plurality of first common connection lines from the plurality of second common connection lines, and (iv) electrically connect the plurality of second common connection lines to each other to independently drive the one or the plurality of first common connection lines and the plurality of second common connection lines from each other, wherein,
