Abstract
The present invention relates to a display panel and a display device. The present invention uses the first shielding portion to shield the electrical field formed by the non-overlapping charge centers of positive and negative ions inside the substrate and the electrical field formed at the interface of different membrane layers, prevents the electrical field from affecting the operating characteristics of the second semiconductor layer, avoiding the phenomenon of afterimage and ESD explosion damage. At the same time, it avoids the problems of poor electrostatic shielding effect of the lower gate electrode and the hump effect and reduction in reliability of the lower channel in conventional technology IGZO TFT.
