    • In a liquid crystal display apparatus, a first control signal bus line receives a first control signal. A second control signal bus line receives a second control signal that lags behind the first control signal. A de-multiplexer circuit includes a first switching element and a second switching element. The first switching element switches a current path between a first source line and a first data line in response to the first control signal, and the second switching element switches a current path between the first source line and a second data line in response to the second control signal. A pixel part includes a first pixel connected to the first control signal bus line and corresponding to a first color filter, a second pixel connected to the second control signal bus line and corresponding to a second color filter, and a third pixel corresponding to a third color filter, wherein the third pixels are alternately connected to the first control signal bus line and the second control signal bus line.

    • A shift register includes a plurality of stages to output a plurality of output signals, in sequence. Each of the stages includes a driving part and a discharging part. The driving part outputs an output signal of a present stage based on one of a start signal and an output signal of a previous stage, and a clock signal. The discharging part discharges the output signal of the present stage. The discharging part includes a discharge transistor and an auxiliary transistor. The discharge transistor has a gate electrode receiving an output signal of a next stage. The auxiliary transistor has a gate electrode receiving the output signal of the next stage. The auxiliary transistor is electrically connected in series to the discharge transistor. Therefore, the chance of a malfunction is decreased, and image display quality of the display device is improved.
    • 移位寄存器包括多个级以依次输出多个输出信号。 每个级包括驱动部和排出部。 驱动部分基于前一级的起始信号和输出信号之一以及时钟信号输出当前级的输出信号。 放电部分对本阶段的输出信号进行放电。 放电部分包括放电晶体管和辅助晶体管。 放电晶体管具有接收下一级的输出信号的栅电极。 辅助晶体管具有接收下一级的输出信号的栅电极。 辅助晶体管与放电晶体管串联电连接。 因此,故障的可能性降低,显示装置的图像显示质量提高。
