Layout structure of shift register

A shift register layout structure comprises an input/output interface layout area; the trigger layout area is adjacent to the input/output interface layout area so as to receive a control signal from the input/output interface layout area and shape the control signal; a data selector territory region adjacent to the trigger territory region and the input/output interface territory region to receive a shaped control signal; the reset function layout area and the clock function layout area are adjacent to the input/output interface layout area; and the register unit layout area is respectively adjacent to the input/output interface layout area, the data selector layout area, the zero clearing function layout area and the clock function layout area. According to the shift register, the control signal is shaped through the trigger layout area, the problem of disorder of a right shift function and a parallel data transmission function is solved, interference to the control signal is reduced through layout optimiza
