Abstract
An active matrix type liquid crystal display device may include a black signal insertion device to apply a voltage corresponding to a black display as a voltage for data signal lines only during a black signal insertion period that is a part of one frame period, a black insertion ratio change device to change the insertion period, and an unchanged-storage-capacitor-phase-keeping device to control the insertion period after the change. The control makes a time difference the same, before and after the change, between (i) a timing, among timings at which signal voltages of the first or second storage capacitor line rise, at which a storage capacitor voltage rises that is both prior to a start timing of the insertion period and a closest timing to the start timing of the insertion period, and (ii) the start timing of the insertion period.
