PROBLEM TO BE SOLVED: To provide a display device which obtains a normal scan signal by reducing a shift amount of a threshold voltage of transistors composing a scan signal line drive circuit formed on the same substrate with a display panel.SOLUTION: In order to stably control a transistor T5 controlled by a first potential node N1, each shift register circuit inputs a clock potential signal by connecting a wiring line 803 to a drain terminal of a transistor T4 so that a voltage in which a state of A>B and A>C and a state of A<B and A<C, or a state of A>B and A<C and a state of A<B and A>C, or a state of A<B and A>C and a state of A>B and A<C, is alternately switched, is applied to a third element of a shift resister, wherein A is a voltage applied to a gate terminal of the transistor T4 which performs control so that the first potential node N1 and a second potential node N2 are opposite to each other, B is a voltage applied to a source terminal thereof, and C is a voltage applied to a drain terminal thereof. |
