PROBLEM TO BE SOLVED: To provide the driving device of a liquid crystal device capable of surely preventing the degradation of display quality such as ghosts or the like by simple constitution even in the case of writing image signals line-sequentially for data lines. SOLUTION: A selection circuit 403 composed of 3-input NAND circuits and a buffer circuit 402 composed of inverters are provided between the respective output stages of a shift register 401 and a sampling circuit 301. The output signal line of the respective output stages of the shift register 401, the output signal line of the output stage adjacent to the output stage and an enable signal ENB outputted from and image control means are connected to the input terminal of the 3-input NAND circuit. Then, the enable signal ENB is a signal in common to all the 3-input NAND circuits, an output timing is within a period in which the output signals of the adjacent output stages are overlapped and a pulse width is necessarily shorter than the period. |
