摘要： A display panel and a display device are provided. Data transfer wires electrically connected to first multiplexers pass through an active area and are electrically connected to data pins arranged in a chip binding area. Therefore, an area occupied by the data transfer wires in the border area is reduced, a space for wiring in the border area can be vacated and the border area can be narrowed. This follows the trend towards increasingly narrow borders of display devices.
