    • 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).
    • 在具有将一个像素分割为多个子像素以提高视角特性的结构的液晶显示装置中,用于驱动面板的IC芯片的数量比传统技术的数量减少。 栅极驱动器具有与第一栅极总线(GLAi)(i = 1〜n)对应的第一移位寄存器(20A),对应于第二栅极总线(GLBi)的第二移位寄存器(20B) 电路(ANDi)各自输出表示来自第一移位寄存器(20A)的输出信号(QAi)与来自第二移位寄存器(20B)的输出信号(QBi)之间的和信号的信号。 对于第一栅极总线(GLAi),将来自第一移位寄存器(20A)的输出信号(QAi)原样应用为扫描信号(GAi)。 向第二栅极总线(GLBi)输入来自“与”运算电路(ANDi)的输出信号作为扫描信号(GBi)。

    • Provided is a shift register configured by cascade-connecting unit circuits 11 each including a compensation circuit 21. The compensation circuit 21 applies an overshoot potential Vos (compensation potential) that is lower than a low level potential to an additional output terminal Z, when a second reset signal R2 outputted from a second next stage unit circuit becomes a high level. To a gate terminal of a TFT T8 (output reset transistor), a signal outputted from the additional output terminal Z included in a next stage unit circuit is supplied. Selectively applying a high level potential and a compensation potential of a polarity opposite to the high level potential to the gate terminal of the TFT T8 allows to reduce a threshold voltage shift of the TFT T8 and to prevent a reset time of the output signal from becoming long over time.
