Abstract
The scan line drive circuit outputs selection signals GVand GVto select scan lines in the display panel. Assuming that a period in which a data voltage SVafter being subjected to inversion of the polarity thereof is supplied to a data line in the display panel is a first period TSD, and that a period in which the data voltage SVafter not being subjected to inversion of the polarity thereof is supplied to the data line is a second period TSC, the period TPD from the start of the first period TSD until the selection signal GVis activated is longer than the period TPC from the start of the second period TSC until the selection signal GVis activated.
