ABSTRACT:
In a liquid crystal display device, sampling means and gate circuits are provided at every signal line, whereby a load in the sampling operation is reduced to carry out the sampling operation with ease. Simultaneously, the charge supplying time to the signal lines can be extended to thereby charge the signal lines by the signals satisfactorily. Thus, the quality of a displayed image can be prevented from being deteriorated.
