    摘要: The present disclosure discloses an optical clear adhesive and a display device. The display device includes: a flexible display panel having at least one foldable area; and an optical clear adhesive disposed on at least one side of the flexible display panel. The optical clear adhesive includes: a substrate layer, a first adhesive material structure and a second adhesive material structure disposed on two opposite sides of the substrate layer, all of which are transparent materials; a deformation recovery rate of the substrate layer is greater than that of each of the first adhesive material structure and the second adhesive material structure; and in the optical clear adhesive, the first adhesive material structure is closer to an inner folding side of the foldable area of a display panel, and the second adhesive material structure is closer to an outer folding side of the foldable area of the display panel.
