1. A liquid crystal display device comprising:

  • a first substrate;

    a second substrate;

    a liquid crystal layer sandwiched between said first substrate and said second substrate;

    a plurality of reflective electrodes arranged on a surface of said first substrate on a liquid crystal layer side thereof, each of said plurality of reflective electrodes being adapted to be supplied with a video signal;

    a counter electrode disposed on a surface of said second substrate on a liquid crystal layer side thereof;

    a plurality of second light-blocking conductive films disposed below said plurality of reflective electrodes with an insulating layer interposed between said plurality of second light-blocking films and said plurality of reflective electrodes; and

    a first light-blocking film disposed below said plurality of second light-blocking conductive films and formed to cover spacing between said plurality of second light-blocking conductive films;

    each of said plurality of second light-blocking films being electrically connected to a corresponding one of said plurality of reflective electrodes, each of said plurality of second light-blocking films being disposed to cover at least a portion of spacings between said corresponding one of said plurality of reflective electrodes and ones of said plurality of reflective electrodes adjacent to said corresponding one of said plurality of reflective electrodes. wherein each of said plurality of second light-blocking films forms a capacitance with said first light-blocking film, and a polarity of a voltage supplied to each of said plurality of second light-blocking conductive films is inverted with respect to a voltage applied on said counter electrode at specified time intervals.
