A liquid crystal display apparatus and a data driver of the present invention is provided with a sampling pulse generating circuit. The sampling pulse generating circuit is provided with a shift register for shift operation having a plurality of set-reset type flip-flops, and analog switches whose opening and closing of each analog switch is controlled in response to each output of the respective flip-flops so that a clock signal is outputted during the opening as a sampling pulse. Sampling of the image signal is carried out in accordance with the sampling pulses. The pulse width of the sampling pulse varies depending on the duty ratio of the clock signal, thereby ensuring to avoid that active periods of the adjoining sampling pulses overlap with each other.
A liquid crystal display apparatus comprising a sampling pulse generating circuit for generating a plurality of sampling pulses that carry out sampling of inputted signal, in which the inputted signal is sampled in accordance with the sampling pulses so as to be written into a display section as a display data,
A data driver comprising a sampling pulse generating circuit for generating a plurality of sampling pulses that carry out sampling of inputted signal, in which the inputted signal is sampled in accordance with the sampling pulses so as to be outputted as a display data,
