Abstract
Disclosed are an array substrate, a display panel, a display device and an array-substrate manufacturing method. The array substrate includes a substrate and a driving-circuit layer including multiple pixel circuits. Each of at least one pixel circuit includes a first thin film transistor and a second thin film transistor. The first thin film transistor includes a first active layer, a first gate electrode, a first A electrode and a first B electrode, and the first active layer includes a low temperature polycrystalline silicon active layer. The second thin film transistor includes a second active layer, a second gate electrode, a second A electrode and a second B electrode, and the second active layer includes an oxide semiconductor active layer.
