Abstract
A stretchable display panel and a display device are provided. The stretchable display panel includes a center display area, a transition display area, and a wiring area, and in a direction from the center display area to the wiring area, a width of bridge structures in the transition display area gradually increases. Island structures located at a peripheral area include an edge bridge structure, and through meeting of adjacent edge bridge structures, a width of the edge bridge structures is increased to increase tensile strength of the edge bridge structures, decreasing risk of wires breaking in the transition display area.
