The invention relates to a display device which enables a poster banner to scroll along the length of a support between two motorized winding shafts which are equipped with means for driving same sequentially in both directions and means for fixing the two ends of the poster banner. Accordingly, to the invention, the support is curved on the side comprising the poster banner, over at least part of the surface thereof. In addition, the support comprises an open-work wall which forms the front wall of a chamber that is intended to be pressurized with air when the winding shafts of the poster banner are actuated
