Abstract
An embodiment of the present invention switches, in a display driving circuit of a liquid crystal display device which carries out CC driving, between a two-line reversal driving mode in which a polarity of a data signal supplied to a source line is reversed every two horizontal scanning periods and a one-line reversal driving mode in which a polarity of a data signal supplied to a source line is reversed every one horizontal scanning period. In at least one example embodiment, a polarity signal reverses its polarity every two horizontal scanning periods in the two-line reversal driving mode, and reverses its polarity every one horizontal scanning period in the one-line reversal driving mode.
