1. A liquid crystal display device comprising:

  • liquid crystal pixels provided at intersections of scanning lines and signal lines arranged in matrix on an insulation substrate, and connected to the signal lines via transistors; and

    a timing control circuit for driving the liquid crystal pixels, wherein said timing control circuit further comprises;

    shift registers consisting of a plurality of flip-flop circuits which are connected in cascade, and each serve to transfer a shift pulse to a next stage sequentially in synchronism with a predetermined clock signal, and output pulses from each stage;

    pulse-overlap detecting circuits for receiving output pulses from flip-flop circuits adjacent to each other, and generating and outputting inverted logical product signals of these output pulses; and

    output circuits, to which output pulses outputted from one of the previous flip-flop circuits of the adjacent flip-flop circuits, and the inverted logical product signal are input, for generating and outputting logical product signals of the output pulses and the inverted logical product signals.
