A shift register and an LCD device to prevent the deterioration of a transistor by controlling a bias stress are disclosed. The shift register includes a plurality of stages for sequential shift signals, wherein each of the plurality of stages is connected with first and second supplying voltage input lines having opposite phases inversed by at least every frame, a start pulse input line, and at least one clock signal input line in which a phase of a first logic state is shifted in sequence, and a clock signal inputted to the clock signal input line is maintained in a second logic state different from the first logic state during a blanking time between frames.
