Abstract: A display panel is provided, including a grounding signal wiring, driving chips, a driving chip input output signal wiring, and a power line. A grounding signal pin is connected to the grounding signal wiring. The driving chip input output signal wiring is configured to connect a stage-transfer signal input pin and a stage-transfer signal output pin of two adjacent driving chips. The grounding signal wiring, the driving chip input output signal wiring, and the power line are disposed in a same layer and do not intersect with each other.

Abstract: A backlight source and a display device are provided. The display panel includes the plurality of stacked metal sub-layers and the first passivation sub-layer and the second passivation sub-layer stacked. The first passivation sub-layer is disposed between the metal layer and the second passivation layer. Material of the first passivation sub-layer includes silicon nitride. The first passivation sub-layer covers the untidy area at the ends of the molybdenum-titanium alloy thin layer to avoid from detachment of the passivation layer, and meanwhile to solve the issues of simplifying the manufacturing process of the display panel, and to avoid from oxidation of the bonding pads.
