ABSTRACT:
A driver circuit for a display device includes a plurality of set-reset flip-flops and switch circuits, and is arranged so that a timing pulse for sampling outputted from the flip-flop is supplied to the switch circuit, so as to cause the switch circuit to receive a clock signal. The clock signal operates as a set signal of the next stage flip-flop and outputted as a control signal for carrying out pre-charging of a data signal line and a selected pixel connected to the data signal line, with a switch. Thus, in case of performing pre-charging of a signal supplying line with an internal pre-charging circuit by using a pre-charging power source having small driving ability, this arrangement can provide a driver circuit for a display device capable of preventing fluctuation of a signal supplied to a different signal supplying line, while keeping the circuit scale of the shift register small.
