Display device and shift register circuit

The invention discloses a display device and a shift register circuit. The shift register storage circuit comprises multi-stage shift register units, wherein each stage shift register unit has a pull-up unit used for outputting a first drive voltage, a drive unit for outputting a first scanning signal, and a voltage regulation unit having an input terminal which is electrically coupled to a voltage source and an output terminal for outputting a second voltage; a first control unit is used for enabling the electric potential of the control terminal of the drive unit to be pulled-down to the first voltage of the voltage source according to a clock pulse signal of a first system; a second control unit is used for enabling the electric potential of the control terminal of the drive unit to be pulled-down to the first voltage of the voltage source according to a clock pulse signal of a second system; a first pull-down unit and a second pull-down unit has an output terminal with a first end electrically coupled to
