Abstract

The active matrix display device has a thin film transistor and a pixel electrode, which is provided with a pixel voltage through the thin film transistor, for each of pixels. A supplemental pixel electrode, which is connected to the pixel electrode of one of the pixels adjacent to each other, and which extends to the region between the two pixels adjacent to each other, is also disposed. The supplemental pixel electrode enables the region between the pixels to be used as a part of the display region. The liquid crystal of this region is also driven by the voltage same as the pixel electrode. The configuration of the peripheral circuit of the pixel portion is simplified, reducing the framing area of the panel.
