1. A display having an expanding device for maintaining the display upright, wherein said display (10) comprises three or more flat panels (11, 12, 13, 14) having lateral edges (15) connected to one another forming corners, and wherein said expanding device (200) comprises a plate (20) having a first hinge (21) dividing said plate (20) into first and second plate portions (20a, 20b), an elastic tensile element (7) pulling said first and second plate portions (20a, 20b) towards each other to fold the plate (20) around said first hinge (21) from a flat folded position to an angled working position, and at least one limiting member (23) which has a connection edge hingedly connected to the first plate portion (20a) by a second hinge (22) and a free edge (23a) which, when the plate (20) is in said angled working position, is in contact with the second plate portion (20b) in order to limit the folding of the plate (20) to said angled working position, wherein said second hinge (22) forms an angle greater than zero degrees with respect to said first hinge (21), and wherein the expanding device (200) is located between at least two adjacent flat panels (11, 12, 13, 14) forming a corner of the display (10) and the first and second plate portions (20a, 20b) of the expanding device (200) are connected to said two adjacent flat panels (11, 12, 13, 14) forming said corner of the display (10) in order to push from within the flat panels (11, 12, 13, 14) from a collapsed position, in which the flat panels (11, 12, 13, 14) have a flat arrangement, to an expanded position, in which the flat panels (11, 12, 13, 14) have a three dimensional arrangement capable of being held upright. |
