Abstract:
A driving circuit that sequentially drives a plurality of switching elements that apply a plurality of image signals to a plurality of pixel electrodes, the driving circuit comprising:a shift register that sequentially provides a plurality of output signals; a plurality of selecting circuits that provide a plurality of driving signals that are derived from the output signals provided by the shift register according to a plurality of enable signals; and a plurality of sampling circuits that provide the plurality of corresponding switching elements with the image signal based on the driving signal outputted from the selecting circuit; each of the plurality of enable signals having a non-rectangular pulse waveform that define times at which the selecting circuits should provide the sampling circuits with the plurality of driving signals, wherein a rising transition of the non-rectangular pulse waveform of the enable signals takes a period of time ranging from 20 ns to 50 ns.
