Array substrate, manufacturing method, and display device

The invention provides an array substrate, a manufacturing method, and a display device. The array substrate comprises a monocrystalline silicon substrate, an array circuit layer, and an anode conducting layer. The monocrystalline silicon substrate is provided with a central display region, a first peripheral region, and a second peripheral region. The central display region comprises a plurality of pixel regions. The array circuit layer is formed on the monocrystalline silicon substrate, and comprises a plurality of transistors which are formed in the monocrystalline silicon substrate in an active region. The array circuit layer forms a scanning drive circuit in the first peripheral region, forms a data drive circuit in the second peripheral region, and forms a pixel circuit in each pixel region. The anode conducting layer is formed on an array circuit layer in each pixel region, and is used for outputting an organic light-emitting layer drive current in each pixel region and reflecting light from an organic light-emitting layer. According to the invention, the integrated manufacturing of the scanning drive circuit and the data drive circuit on the substrate is achieved, and the improvement of display performance is facilitated.
