Abstract
A display panel and a display device are provided. The present disclosure reduces the magnitude of an electric field formed between a second active layer and a first gate, and improves the stability of a thin film transistor (TFT) formed by the second active layer, the first gate, a second source, and a second drain. Accordingly, the present disclosure solves a problem in conventional oxide TFTs by preventing a TFT device formed by a bottom gate from having poor reliability.
