Abstract

Pixel circuit, display panel and display device are provided. The pixel circuit includes a driving module, a data writing module, a first reset module, a threshold compensation module, light emitting control modules, a leakage suppression module, a storage capacitor, a first capacitor, and a light emitting module. A first terminal of the first reset module is electrically connected to a reference signal terminal. A first terminal of the threshold compensation module is electrically connected to a second terminal of the driving module. A control terminal of the driving module is electrically connected to a first node. A second terminal of the first reset module and a second terminal of the threshold compensation module are both electrically connected to the first node through the leakage suppression module. A connection node between the leakage suppression module and the second terminal of the first reset module is a second node.
