Abstract
A shift register circuit that controls back gate voltage of a transistor with a simple configuration and at a low cost, and a display panel. In the shift register circuit, shift registers include: an output circuit, a charge and discharge circuit, a first power supply terminal, and at least one back gate voltage generation circuit. The output circuit or the charge and discharge circuit includes at least one transistor. The back gate voltage generation circuit includes a back gate node. The back gate node is connected to the back gate electrode of the transistor. The back gate voltage generation circuit changes a voltage of the back gate node according to a voltage of a gate electrode of the transistor. The back gate voltage generation circuit is supplied with a drive voltage from the first power supply terminal.
