Abstract:
An active matrix display device with a plurality of gradational levels, said device comprising:a plurality of pixels being arranged in a matrix form,each of the plurality of pixels having a pixel electrode and a thin film transistor being connected to the pixel electrode,said thin film transistor including:a source region, a drain region, and a channel region being interposed between the source and drain region,a gate electrode being formed adjacent to at least the channel region with a gate insulating film interposed therebetween,wherein a current flows between the source region and the drain region while the thin film transistor turns off,wherein a signal voltage supplied to the gate electrode is delayed in fall of a signal waveform, so that the current flows to correct a feed through voltage .DELTA.Vs, whereby, the feed through voltage .DELTA.Vs is set lower than a voltage Vgr necessary for realizing a single gradation.
