An information display device (1) including a sheet (2) of material rolled-up on a drum (3) received in a housing (6) is described, characterised in that the housing (6) has a means (9) for receiving one or more members (5B) of a strut (5), the receiving means (9) has an aperture (10) for loading and unloading the strut members (5B), which aperture (10) has a cross-section substantially larger than the strut member (5A) in a longitudinal plane, so as to enable said strut member (5A) to extend therethrough, and the receiving means (9) is arranged in relation to the housing (6) so that the aperture (10) is adjacent to the slot (7) through which the sheet (2) extends, and the rigid, elongated part (8) associated with the upper edge of the sheet (2), in the rolled-up position of said sheet (2), at least partially seals the aperture (10) of the receiving means so as to prevent unloading of the members (5A) of strut (5) therefrom.
