Abstract

There is provided a driving circuit which is simple and has a small occupied area. A shift register circuit of the present invention includes a plurality of register circuits. Each of the register circuits includes a clocked inverter circuit and an inverter circuit. Both are connected in series with each other so that an output signal of the clocked inverter circuit becomes an input signal of the inverter circuit. Further, the register circuit includes a signal line by which an output signal of the inverter circuit is transmitted. Since a number of elements are connected to the signal line and parasitic capacitance is large, it has a high load. The shift register circuit of the present invention uses the fact that since the parasitic capacitance of the signal line is large, it has a high load.
