ABSTRACT:
At least one of a scanning-line drive part and a data-line drive part includes: a shift register for outputting transfer signals in sequence; a first enable supply line for supplying a plurality of series of first enable signals having a first pulse width smaller than that of the transfer signals; a second enable supply line for supplying one series of second enable signal having a second pulse width smaller than the first pulse width; and pulse-width restricting circuits for receiving input of the transfer signals, the first and the second enable signals. The pulse-width restricting circuits restricts the pulse width of the transfer signals to the first pulse width by shaping each pulse of the input transfer signals based on the individual first enable signals, and restricts the pulse width of the transfer signals to the second pulse width by shaping all the pulses of the transfer signals after restricted to the first pulse width based on the second enable signal.
