<p>PURPOSE:To prevent a liq. crystal included in dummy pixels from being impressed with DC component. CONSTITUTION:This active type liq. crystal display device has a panel structure provided with a driving substrate, a counter substrate and liq. crystal held between them, an effective display part 1 visible from an outside when it is seen planarily and a circumferential non-effective display part 2 masked from the outside. The driving substrate is provided with gate lines X of row shapes and signal lines Y of column shapes over the effective display part 1 and the non-effective display part 2 and defines pixel area at each intersecting part between them. A pixel electrode and a thin film transistor Tr driving the pixel is formed in an individual pixel area belonging to the effective display part 1 to constitute a real pixel 3 contributing to a display. Besides, a thin film transistor Tr is formed in a state where a pixel electrode is lacked in an individual pixel area belonging to the non-effective display part 2 to constitute a dummy pixel 5 which does not contribute to the display.</p> |
