Abstract:
The present disclosure discloses a display panel and a display device. The display panel includes pixel circuits arranged in an array. Each pixel circuit includes a driving transistor, at least two switching transistors and at least two first auxiliary electrodes arranged in a one to one relationship to the switching transistors. By electrically connecting each of the first auxiliary electrodes with a gate of a related switching transistor, the first auxiliary electrode and the gate of the corresponding switching transistor have a same potential. A capacitor can be formed between the first auxiliary electrode and the active layer, and a capacitor is formed between the gate and the active layer.
