Abstract
Official abstract text for this publication.
In each pixel formation portion of a display device, an amplification electrode is provided which is connected to a drain electrode of a thin-film transistor whose gate electrode is connected to a gate bus line and whose source electrode is connected to a source bus line. A second-capacitor is formed by the amplification electrode and a pixel electrode. A selection period is constituted by a precharge period and an amplification period. In the precharge period, a video signal potential is applied to the pixel electrode and a potential of a control wire is applied to the amplification electrode. In the amplification period, a video signal potential is applied to the amplification electrode with the pixel electrode being in a floating state.
First claim
Opening claim text (preview).
The invention claimed is: 1. An active matrix-type display device which has a plurality of video signal lines; a plurality of scanning signal lines intersecting with the plurality of video signal lines; a plurality of pixel formation portions arranged in a matrix form corresponding respectively to intersections of the plurality of video signal lines and the plurality of scanning signal lines; and a common electrode commonly provided in the plurality of pixel formation portions, the…
