Abstract
A gate-line drive circuit is driven by three clock signals of different phases, and includes a plurality of cascade-connected unit shift registers. In a normal operation, activation periods of the three clock signals do not overlap one another. However, the two clock signals of them are simultaneously activated at the beginning of a frame period. A unit shift register of the first stage is adapted to activate an output signal in accordance with the simultaneous activation of the two clock signals.
