摘要

The present invention switches, in a display driving circuit of a liquid crystal display device which carries out CC (Charge Coupling) driving, between a two-line (2H) reversal driving mode in which a polarity of a data signal (S) supplied to a source line is reversed every two horizontal scanning periods and a one-line (1H) reversal driving mode in which a polarity of a data signal (S) supplied to a source line is reversed every one horizontal scanning period. A polarity signal (CMI) reverses its polarity every two horizontal scanning periods in the two-line (2H) reversal driving mode, and reverses its polarity every one horizontal scanning period in the one-line (1H) reversal driving mode.
