The reinforcing film (10) is provided with an adhesive layer (2) fixedly laminated on the film substrate (1). The adhesive layer is a photocurable composition and contains a (meth)acrylic base polymer, a (meth)acrylic oligomer, and a polyfunctional compound. When the adhesive layer is divided into three equal parts in the thickness direction, and the area farthest from the substrate side is used as the surface area, it is preferable that the amount of the polyfunctional compound in the surface area is the multifunctional in the entire thickness direction The amount of the compound is more than 50%, and the amount of (meth)acrylic oligomer in the surface region is 31% or less of the amount of (meth)acrylic oligomer in the entire thickness direction. |
