Active matrix display device with floating electrode between adjacent pixels
First Claim
1. An active matrix display comprising:
- a plurality of pixels;
a thin film transistor provided for each of the pixels;
a pixel electrode provided for each of the pixels;
a liquid crystal layer disposed on the pixel electrodes;
a floating electrode disposed to cover a region between two adjacent pixels and forming a capacitive coupling with each of the pixel electrodes of the two adjacent pixels;
a plurality of data lines connected with corresponding thin film transistors; and
an insulating layer disposed between the floating electrode and the two corresponding pixel electrodes,wherein the floating electrode is disposed partially under each of the two corresponding pixel electrodes such that no wiring, other than the pixel electrodes, is disposed between the liquid crystal layer and the floating electrode, andthe insulating layer is in contact with the floating electrode and the data lines.

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.
