Abstract: An embodiment of the present application discloses a display panel and a display panel manufacturing method. The photosensitive element and the thin film transistor device are disposed on the same side of the substrate. Some components of the photosensitive element and some components of the thin film transistor device can be manufactured by the same step, and therefore can improve integration of the photosensitive element on the array substrate. Furthermore, the photosensitive element can be integrated in the display panel with reduced photomasks and a lowered cost.

Abstract: Embodiments of the present disclosure are directed to a display panel and a display device. The first fan-out wire in a first area is designed as a first portion of the first metallic layer and a second portion of a second metallic layer. The first portion of the first metallic layer is coupled to the second portion of the second metallic layer. The width of the first fan-out wire in the first area is less than the width of the fan-out wires in other areas. The distance between the first fan-out wires in the first area is less than the distance between the first fan-out wires in the other areas. While the impedance of the first fan-out wire is not increased or even reduced, the space occupied by the first fan-out wire is reduced.
