    • In a gate driving circuit and a display apparatus having the gate driving circuit, a pull-up transistor of a present stage among plural stages, which are connected one after another to each other and sequentially output a gate signal, pulls up a present gate signal output through an output terminal to a gate-on voltage. A buffer transistor is connected to a control terminal of the pull-up transistor to receive a previous output signal from a previous stage and to turn on the pull-up transistor. The buffer transistor has a chargeability that is about two times or greater than the chargeability of the pull-up transistor. Thus, the size of the pull-up transistor may be reduced, thereby preventing a malfunction of the gate driving circuit when the gate driving circuit is operated under conditions of high temperature or low temperature.
    • 在具有栅极驱动电路的栅极驱动电路和显示装置中,将多个相互依次连接并依次输出栅极信号的多级中的当前级的上拉晶体管拉起当前的栅极信号 通过输出端子输出到栅极导通电压。 缓冲晶体管连接到上拉晶体管的控制端,以接收来自前一级的先前输出信号并接通上拉晶体管。 缓冲晶体管具有的电荷率约为上拉晶体管的充电能力的两倍或更大。 因此,可以减小上拉晶体管的尺寸,从而当栅极驱动电路在高温或低温条件下工作时,防止栅极驱动电路的故障。

    • Provided are a thin-film transistor (TFT) substrate and a display device having the same. In the TFT substrate and the display device having the same, first and second drain electrodes of first and second TFTs connected to first and second pixel electrodes, respectively, are vertically bent a plurality of times. The distance between each of the first and second source electrodes and the first or second drain electrode is maintained at a minimum interline gap to increase the distance between a data line and each of the first and second drain electrodes and minimize the length of a region of each of the first and second drain electrodes adjacent to the data line. Consequently, a coupling capacitance between the data line and each of the first and second drain electrodes can be reduced, and each unit pixel region can have a uniform parasite capacitance within a predetermined range. In addition, the luminance deviation of a display device, which performs inversion driving, can be reduced.
