Active matrix liquid crystal display device with independent potentials applied to the opposing electrode and the transistor side conductive light shielding film

An active matrix type liquid crystal display device having a plurality of liquid crystal elements, each of said liquid crystal elements comprising:

• a transistor section having a gate electrode, a gate insulating film, a semiconductor film, a source electrode, a drain electrode, and a passivation insulating film;
• a first conductive light shielding film electrically coupled to said transistor section and having an open portion;
• a pixel electrode formed over said open portion of said first conductive light shielding film and electrically connected to said source electrode of said transistor section;
• a liquid crystal layer formed on said passivation insulating film;
• an opposing electrode formed on said liquid crystal layer;
• and
• a means to apply to said first conductive light shielding film a potential independent of a potential applied to said opposing electrode
• wherein, during operation of said first conductive light shielding film, a voltage of said first conductive light shielding film is capable of being different from a voltage of said opposing electrode, thereby, reducing disclination in said liquid crystal elements.
