Display panel and manufacturing method thereof

A manufacturing method of a display panel, comprising following steps:

• providing a substrate, wherein the substrate is divided into a transparent region, a wiring changing region, and a display region, wherein the wiring changing region encircles the transparent region, the display region encircles the wiring changing region, and the display region have a first position and a second position;
• forming an active layer and a first insulation layer on the substrate;
• forming a plurality of metal conducting wires and a plurality of insulating layers on the first insulation layer;
• forming a first line segment and a second line segment of a first signal conducting wire on the plurality of insulating layers, wherein the first line segment extends to the wiring changing region from the first position of the display region, the second line segment extends to the second position of the display region from the wiring changing region, and forming a planarization layer on the first line segment, the second line segment, and the plurality of insulating layers;
• and
• forming a first anode wiring of the first signal conducting wire on the planarization layer and in the wiring changing region, wherein the first anode wiring is electrically connected to the first line segment and the second line segment.
