Array substrate, display panel and manufacturing method thereof

An array substrate, comprising a display region and a peripheral region located at a periphery of the display region, the array substrate comprising:

• a plurality of data lines, located at least in the display region, wherein the plurality of data lines is arranged along a first direction;
• a plurality of gate lines, located at least in the display region, wherein the plurality of gate lines is arranged along a second direction, and the second direction intersects with the first direction;
• a gate driving structure, located in the peripheral region and at at least one side of the display region in the first direction, wherein the gate driving structure is configured to be electrically connected with the plurality of gate lines;
• a plurality of gate driving signal lines, located in the peripheral region and electrically connected with the gate driving structure, wherein the plurality of gate driving signal lines comprises a first gate driving signal line portion and a second gate driving signal line portion which are respectively located at both sides of the gate driving structure in the second direction;
• a first data fanout wiring region, located in the peripheral region, wherein wires in the first data fanout wiring region are configured to be electrically connected with the plurality of data lines;
• a second data fanout wiring region, located in the peripheral region, wherein wires in the second data fanout wiring region are configured to be electrically connected with the plurality of data lines, and the first data fanout wiring region and the second data fanout wiring region are located in the peripheral region on opposite sides, respectively,
• wherein the array substrate further comprises a common signal transmission line located between the display region and the gate driving structure, one end of the common signal transmission line is electrically connected with a pad close to the first gate driving signal line portion, and the other end of the common signal transmission line is electrically connected with a pad close to the second gate driving signal line portion,
• a count of pads between the common signal transmission line and the first gate driving signal line portion is a first number, a count of pads between the common signal transmission line and the second gate driving signal line portion is a second number, and the first number is the same as the second number.
