Abstract
In at least one embodiment a ripple, generated in an electric potential of data signal lines even in long-term reversal driving, is reduced and display quality is improved. In at least one example embodiment, the liquid crystal display apparatus of the present invention includes scanning signal lines and data signal lines, in which one scanning pulse is outputted to select one scanning signal line, each of the data signal lines receives data signals whose polarities are reversed per one vertical scanning period while in one horizontal scanning period, one of two data signal lines receives a data signal having a polarity and the other of the two data signal lines receives another data signal having another polarity, the two data signal lines being arranged adjacent to each other, scanning pulses are successively outputted in sets of two, and at a timing in which two scanning pulses fall, two scanning pulses rise.
