Abstract

Embodiments of the present disclosure are directed to a display panel and a display device. A width of the fan-out wire positioned at the outer side is increased such that the impedance of the outer fan-out wire could be reduced. Furthermore, the second part of the second fan-out wire is bended in a direction away from the display region.
