1. A liquid-crystal active-matrix display device comprising:

  • picture element electrodes; and

    thin film transistors, each including a gate, source and drain electrode and each corresponding to one of said picture element electrodes, for switching voltages applied to each corresponding picture element electrode;

    said thin film transistors and corresponding picture element electrodes being arranged in a matrix format on a substrate;

    said thin film transistors being connected to gate lines and source lines at intersections thereof, the gate lines each connecting a plurality of said gate electrodes and the source lines each connecting a plurality of said source electrodes;

    said drain electrodes being connected to said picture element electrodes;

    said gate electrodes and non-corresponding adjacent picture element electrodes overlapping at edge portions thereof to form additional capacitors, with a first insulating film and a second insulating film being interposed therebetween.
