Abstract
The invention discloses an array substrate and a manufacturing method thereof and a display device, which can solve the problems such as complicated, high cost, time-consuming process in the prior art, and increase the storage capacitance. In the array substrate, data lines and a common electrode line are provided in the same layer on the base substrate and below an active layer, the data lines and the common electrode line are provided separately, the common electrode is provided with a connection part which partly overlaps with the common electrode line in an orthographic projection direction, and the common electrode is electrically connected to the common electrode line through a first via between the connection part and the common electrode line.
