    摘要： The present application provides an array substrate and a display panel. The array substrate includes a substrate, a first gate electrode, a first insulating layer, a first electrode, a second gate electrode, a first conductive channel, and a second electrode. The present application reduces a leakage current of the array substrate by using an orthographic projection of the first gate electrode on the substrate to overlap an orthographic projection of the first conductive channel on the substrate.
