Patent ID: 7466371

Claim:
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.
