A self-expanding foldable structure for a display has a structure that includes a pair of side walls (2) hinged at respective connection edges (2a) to opposing edges of a back wall (1) and a shelf (3) linked to the back and side walls (1, 2) such that they can adopt a flat position in which the back wall, side walls and shelf (1, 2, 3) are substantially coplanar and an expanded position in which the back wall, side walls and shelf (1, 2, 3) form respective dihedrons. An elastic element is arranged to push the structure to the expanded position. The side walls (2) comprise a transverse fold line (14) having one or more scored sections (14a) wherein an inner structure of the wall material is crushed, in combination with one or more cut sections (14b) wherein said inner structure of the wall material has flat edges that can mutually face and support one another in the expanded position.
