Liquid crystal display device

A liquid crystal display device comprising:

• a first substrate;
• a plurality of display pixels formed on the first substrate to form a display pixel region, each of the display pixels comprising a pixel selection transistor and a pixel electrode connected with the pixel selection transistor;
• a plurality of dummy pixels formed on the first substrate to form a dummy pixel region adjacent the display pixel region, each of the dummy pixels comprising a pixel selection transistor and a pixel electrode connected with the pixel selection transistor and being covered by a black matrix to prevent light emission from the dummy pixels;
• a driving transistor formed on the first substrate and supplying a driving signal to the pixel selection transistors of the display pixels, a portion of a channel region of the driving transistor being disposed under part of a pixel electrode of a corresponding dummy pixel;
• an insulation film disposed between the driving transistor and the pixel electrodes of the display and dummy pixels;
• a second substrate;
• and
• a liquid crystal layer disposed between the pixel electrodes of the display and dummy pixels and the second substrate.
