ABSTRACT:
An active matrix display device including a pixel unit which includes row-type gate lines, column-type signal lines and pixels arranged at respective intersecting portions of the gate lines and the signal lines. A vertical scan circuit that successively scans the gate lines to select one row every horizontal period. A horizontal scan circuit supplies video signals to the signal lines. A shift register operates in accordance with a primary clock signal to successively output primary sampling pulses. A phase adjusting unit performs phase adjustment on the primary sampling pulse in accordance with a secondary clock signal to output phase-adjusted pulses which are the primary sampling pulses after the phase adjustment.
