Abstract
In a liquid crystal display device in which one pixel is divided into a plurality of sub-pixels, power consumption is reduced. A liquid crystal display device in which a pixel formation portion forming one pixel includes a first sub-pixel portion and a second sub-pixel portion is provided with a charge sharing circuit () for short-circuiting a CS bus line (CSL) provided for the first sub-pixel portion and a CS bus line (CSL) provided for the second sub-pixel portion to each other based on a short-circuit control signal (CTL). A CS voltage generating circuit () generates CS signals (CSand CS) whose potentials change every predetermined period. The charge sharing circuit () short-circuits the CS bus line (CSL) and the CS bus line (CSL) to each other at timing at which the potentials of the CS signals (CSand CS) change, based on the short-circuit control signal (CTL).
