A display unit back wall includes in a structure reinforced by stiffener bars two parallel uprights forming at least part of a slideway for a plurality of stacked slats, the two uprights forming the two lateral sides of a U-shape unitary construction frame. A crossmember is fixed to the bottom ends of the two uprights. The stiffener bars fixed to the uprights and to the crossmember are all within the peripheral edge of the frame. The U-shape unitary construction frame is made from channel-section, and each side of the slideway is formed between one of the two flanges of the upright and a facing side of the associated stiffener bar.
