Abstract: A display panel and a manufacturing method are provided. The display panel includes an array substrate, gate signal lines, and gate driving circuits. The array substrate includes a display area and a non-display area around the display area. The display area has a geometric center and an outline between the display area and the non-display area. The gate signal lines are disposed in the display area, and each gate signal line intersects the outline of the display area to form at least one intersection point. The gate driving circuits are disposed in the non-display area and respectively electrically connected to the gate signal lines, and each gate driving circuit has a positioning line. For a gate driving circuit and at least one intersection point that correspond to the same gate signal line, the positioning line is aligned with a line segment that connects the intersection point and the geometric center.
