Reflective type liquid crystal display device

A liquid crystal display device comprising:

• a driving-circuit substrate;
• a transparent substrate;
• a liquid crystal layer sandwiched between said driving-circuit substrate and said transparent substrate;
• a plurality of reflective electrodes arranged on a surface of said driving-circuit substrate on a liquid crystal layer side thereof;
• a counter electrode disposed on a surface of said transparent substrate on a liquid crystal layer side thereof;
• a plurality of semiconductor switching elements disposed below said plurality of reflective electrodes, each of said plurality of semiconductor switching elements being configured to supply a video signal to a corresponding one of said plurality of reflective electrodes;
• a first light-blocking film for covering said plurality of semiconductor switching elements;
• and
• a plurality of second light-blocking films each disposed to cover at least a portion of spacings between adjacent ones of said plurality of reflective electrodes,
• each of said plurality of second light-blocking films being electrically connected to a 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 said video signal supplied to each of said plurality of reflective electrodes is inverter with respect to a voltage applied on said counter electrode by varying a voltage supplied to said first light-blocking film.

A liquid crystal display device comprising:

• a first substrate;
• a second substrate;
• spacers made of resin for establishing a spacing between said first substrate and said second substrate;
• a peripheral frame made of said resin and interposed between said first substrate and said second substrate;
