The present application discloses a display panel, an array substrate, and a manufacturing method thereof. In the display panel of the present application, capacitance of a array substrate is formed between a first common electrode and a pixel electrode, and a second electrode layer is provided with a second common electrode in a same layer as a drain electrode and a source electrode, and the first common electrode is connected to the second common electrode, which can prevent a difference between positive and negative polarities of the first common electrode and the pixel electrode, thereby solving the problem of horizontal crosstalk.
