    • The invention provides a liquid crystal display device that includes an IGZO-GDM which can quickly remove a residual charge in a panel when the power supply is turned off, and a driving method of the liquid crystal display device. Each bistable circuit that configures a shift register includes a thin film transistor TI for increasing a potential of an output terminal based on a first clock, a region netA connected to a gate terminal of the thin film transistor TI, a thin film transistor TC for lowering a potential of the region netA, and a region netB connected to a gate terminal of the thin film transistor TC. In such a configuration, a power supply off sequence includes a display off sequence and a gate off sequence. The gate off sequence includes at least a gate-bus-line discharge step (t14 to t15), a netB discharge step (t15 to t16), and a netA discharge step (t16 to t17).
    • 本发明提供了一种液晶显示装置,其包括IGART-GDM,其可以在电源关闭时快速去除面板中的残留电荷,以及液晶显示装置的驱动方法。 配置移位寄存器的每个双稳态电路包括用于基于第一时钟增加输出端子的电位的薄膜晶体管TI,连接到薄膜晶体管TI的栅极端子的区域netA,用于降低的薄膜晶体管TC 区域netA的电位和连接到薄膜晶体管TC的栅极端子的区域netB。 在这种配置中,电源断开序列包括显示关闭序列和关闭序列。 栅极截止序列至少包括栅极总线放电步骤(t14至t15),netB放电步骤(t15至t16)和netA放电步骤(t16至t17)。

    • Picture element electrodes (7) are electrically connected with drain electrodes (18D) of respective transistor elements (18). The picture element electrodes (7) and data signal lines (SLn, SLn+1, . . . ) are provided above scanning signal lines (GLn, GLn+1, . . . ). The picture element electrodes (7) overlap scanning signal lines (GLn, GLn+1, . . . ) when viewed from above. Notch parts 7a and 7b are provided in each picture element electrode (7) so as to overlap each of the scanning signal lines (GLn, GLn+1, . . . ). Shield electrodes (4a, 4b) are formed in the same layer as the data signal lines (SLn, SLn+1, . . . ). Each of the scanning signal lines (GLn, GLn+1, . . . ) at least partially overlaps the shield electrodes (4a, 4b) in the notch parts (7a, 7b), when viewed from above. This provides the liquid crystal display panel having wide viewing angle characteristic and carrying out high quality display.
