ABSTRACT:
In a semiconductor integrated circuit device having at least one shift register, a plurality of 5 stages of the shift register are electrically connected in series, the 1st stage of said shift register is located in the closest position to the data input terminal, and other succeeding stages are sequentially and straightly located at intervals; the chain of the stages is folded at a particular stage, and further succeeding stages are sequentially and straightly located at intervals so as to fill in the spaces between the other stages, thus, the unbalance of the load capacitance between said stages and the functional unbalance between the shift registers can be minimized.
