The present application provides an array substrate and a display panel. The array substrate includes a substrate, an active layer, a first metal layer, a second metal layer, a flexible material layer, and a source/drain layer which are disposed in a stack. The active layer forms a source and a drain and connected to a first connection member formed by the second metal layer through a first through-hole. The first connection member is connected to a doped region of the active layer by a second through-hole. An aperture of the first through-hole is greater than an aperture of the second through-hole. Therefore, a technical problem of a poor connection between the source/drain and the active layer is relieved.
