• a second gap is provided between a first support plate and the rigid support part;
• and orthographic projections of the two first support plates on the flexible display panel are located in the flat area;
• and
• a flexible cladding layer, wrapped around the rigid support part and the two first support plates, joining a side, close to the flexible display panel, of the rigid support part, and sides, close to the flexible display panel, of the two first support plates as a whole;
• wherein:
• the plurality of rigid support strips comprises three rigid support strips;
• a surface, close to the flexible display panel, of at least one of the three rigid support strips is part of a cylindrical surface;
• the part of the cylindrical surface protrudes toward the flexible display Panel;
• a central angle corresponding to the part of the cylindrical surface is less than or equal to 60 degrees;
• and
• the flexible cladding layer comprises:
• a second inclined surface, on a side surface of at least one of the plurality of rigid support strips, adjacent to the first support plate, with an inclination angle greater than or equal to 22.5 degrees;
• a first inclined surface, on a side surface of any one of the plurality of rigid support strips excluding the second inclined surface, with an inclination angle greater than or equal to 22.5 degrees;
• and
• a third inclined surface, on a side surface, close to the rigid support part, of one of the two first support plates, with an inclination angle greater than or equal to 22.5 degrees.
