Abstract:
A display device, comprising:at least one driver circuit comprising a plurality of driver TFTs formed over a substrate; a pixel portion comprising a plurality of pixel TFTs, a plurality of gate signal lines, a plurality of source signal lines, and a plurality of pixel electrodes formed over the substrate, the pixel TFTs and the pixel electrodes disposed on the respective portions where the gate signal lines and the source signal lines cross each other, wherein each n-channel TFT of the driver TFTs has at least one LDD region (low-density imparity region) overlapping with a gate electrode thereof, and each of the pixel TFTs has LDD regions not overlapping with a gate electrode thereof, wherein first video signals of the same polarity are supplied to said plurality of pixel electrodes through said plurality of source signal lines during a first frame period, wherein second video signals of the polarity opposite to that of said first video signal are supplied to said plurality of pixel electrodes through said plurality of source signal lines during a second frame period subsequent to said first frame period, and wherein a length of said first frame period and said second frame period is set to 8.3 msec or less.
