Abstract: A flexible display panel and a display device are provided. The flexible display panel includes: a first flexible substrate, a second flexible substrate, and an inorganic layer located between the first flexible substrate and the second flexible substrate; where there are a plurality of grooves and/or through-holes in the inorganic layer; and the first flexible substrate contacts the second flexible substrate through the grooves and/or the through-holes. In this way, the grooves and/or the through-holes are arranged in the inorganic layer so that the first flexible substrate can contact with the second flexible substrate through the grooves and/or the through-holes to thereby increase the contact area between the second flexible substrate and the inorganic layer so as to alleviate the risk of the organic layer being stripped off the inorganic layer in the flexible display panel being bent and deformed.
