Abstract:
In a liquid crystal display device having a configuration in which one pixel is divided into a plurality of sub-pixels to improve the view angle characteristic, the number of IC chips for driving a panel is reduced more than that in the conventional technique. A gate driver is provided with a first shift register (20A) corresponding to first gate bus lines (GLAi) (i=1 to n), a second shift register (20B) corresponding to second gate bus lines (GLBi), and AND operation circuits (ANDi) each outputting a signal indicating AND between an output signal (QAi) from the first shift register (20A) and an output signal (QBi) from the second shift register (20B). To the first gate bus line (GLAi), the output signal (QAi) from the first shift register (20A) is applied as it is as a scanning signal (GAi). To the second gate bus line (GLBi), an output signal from the AND operation circuit (ANDi) is applied as a scanning signal (GBi).
