<p>The support includes at least one panel of a substantially rigid and foldable material comprising said display face (14). The support can be brought from a folded state into an unfolded state under the action of devices (25-27) performing their actions discretely distributed along the display face (14). Each device (25-27) comprises stressing means, for unfolding the support, and means for keeping the support in its unfolded state, the folding of the support taking place counter to the action of the stressing means of said devices (25-27). These devices (25-27) consist of single spacers fixed to at least one of the faces (15) and are arranged so as to be able to move between a stressed state, with the support in the folded state, and a rest state, in which they keep the support in the unfolded state.</p> |
