1. a shift register cell comprises input end, output terminal, the first clock signal input terminal, second clock signal input part, electronegative potential link and reset terminal, it is characterized in that this shift register cell also comprises:

  • The first film transistor, its first electrode connects input end, and grid connects described second clock signal input part;

    The second thin film transistor (TFT), its first electrode connect transistorized the second electrode of described the first film, and grid connects described reset terminal, and the second electrode connects described electronegative potential link;

    The 3rd thin film transistor (TFT), its second electrode connects described output terminal, and the first electrode connects the first clock signal input terminal, and grid connects transistorized the second electrode of described the first film;

    The 4th thin film transistor (TFT), its first electrode connects described output terminal, and grid connects described reset terminal, and the second electrode connects described electronegative potential link;

    The 5th thin film transistor (TFT), its grid connects the second clock signal input part, and the first electrode connects described output terminal, and the second electrode connects described electronegative potential link;

    Electric capacity, it is connected between the grid and the second electrode of described the 3rd thin film transistor (TFT);

    Wherein, from the first clock signal of described the first clock signal input terminal input with from the second clock signal of described second clock signal input part input identical inversion signal of cycle each other.
