Abstract: A display panel, a manufacturing method of the display panel, and a display device are provided. The display panel includes a display area and a non-display area. The non-display area surrounds the display area. The display panel further includes: a substrate; a first thin film transistor (TFT) disposed in the non-display area, where the first TFT includes a first drain layer placed on one side of the substrate; a second TFT arranged in the display area, where the second TFT includes a second gate layer placed on one side of the substrate. The first drain layer and the second gate layer are arranged in a same layer. By forming the second gate layer and the first drain layer in a same process, the number of photomask processes can be reduced compared to the conventional display panel. This reduces the number of steps.
