Abstract
There are provided a shift register unit and a display device in embodiments of the present disclosure, for solving the problem that since two different transistors are used to respectively pull-up and pull-down a gate line connected to a conventional shift register unit, the conventional shift register unit occupies a large area, which causes a large consumption of materials when manufacturing the shift register unit, a high cost of the conventional shift register unit, and a high cost of a display device comprising the conventional shift register unit. The shift register unit comprises: a first capacitor, a first transistor, a pull-up module and a first pull-down module, wherein the first capacitor has a first electrode configured to receive a clock signal, a gate connected with one terminal of the first capacitor, the pull-up module and the first pull-down module, and a second electrode connected with the other terminal of the first capacitor. The first transistor in the shift register unit pull-up or pull-down the level at the gate line connected to the shift register unit.
