ABSTRACT:
The present invention provides a display apparatus including a pixel array unit, a vertical driving circuit, and a horizontal driving circuit. The horizontal driving circuit includes a shift register for performing shift operation in synchronism with the clock signal and sequentially outputting shift pulses from respective shift stages, a shaping switch group for shaping the shift pulses sequentially outputted from the shift register and sequentially outputting non-overlap sampling pulses temporally separated from each other, and a sampling switch group for sequentially sampling the input video signal in a non-overlapping manner in response to the sampling pulses and supplying the sampled video signal to each of the signal lines. A capacitance interposed between adjacent signal lines is connected to wiring of lower impedance than a signal line side, thereby attenuating capacitive coupling between the adjacent signal lines and thus suppressing the potential variation of the video signal sampled in a non-overlapping manner and supplied to the signal lines.
