Gate drive circuit, display panel and display device

The utility model relates to the technical field of display, and discloses a gate drive circuit, a display panel and a display device.The gate drive circuit comprises a shifting register unit and a level control unit, and the shifting register unit comprises a scanning shifting register and a virtual shifting register; the level control unit is electrically connected with a first scanning input signal line and a second scanning input signal line of the scanning shift register and the virtual shift register, and is configured to input different signals to the first scanning input signal line and the second scanning input signal line under the driving of different control signals. In this way, after transistors used for frame reset in the scanning shift register and the virtual shift register are removed, frame reset processing is performed on the scanning shift register and the virtual shift register in combination with different conduction conditions of the level control unit, so that the number of tubes in the gate drive circuit is reduced, the cost is saved, and the reliability of the gate drive circuit is improved. And the panel yield is improved.
