Deployable display with an expansion system comprising a traction elastic element. The elastic element is basically formed by an elastic band which is annular or is cord-type with engaging elements, and optionally by at least one extension for extending the length of said band, formed by a plate made of flexible or semi-flexible sheet material provided with engaging elements for said elastic band, the assembly in turn being engaged to side projections of the display. The limiting system is implemented by the reduction in the elastic force and/or by the own resting length of the elastic band in cooperation, where appropriate, with the length of the extension element.
