In a shift register that requires a plurality of start pulses and a gate line driving circuit using the same, the number of start pulses that must be input from the outside is reduced. A gate line driving circuit 30 receives two start pulses having different phases, shift registers SR 1 , SR 2 ,... Required for the operation, and a first start pulse SP1 input from the outside, and delays it. And a start pulse generation circuit 32 for generating a second start pulse SP2 to be activated. The shift registers SR 1 , SR 2 ,... Operate based on the first start pulse SP 1 input from the outside and the second start pulse SP 2 generated by the start pulse generation circuit 32.
