a flexible display foil in OLED technology comprising a front side having a display surface and a rear side and an upper end portion adjoined by a main portion of the display foil extending to a lower end of the display foil,
a flexible display foil carrier being attached to the display foil at the rear side thereof or being connected thereto by means of an intermediate layer of, in particular, elastic material and being provided with an upper end portion, which is adjoined by a main portion of the display foil carrier extending to a lower end of the display foil carrier, wherein the upper end portion of the display foil carrier abuts against the upper end portion of the display foil and is or can be stiffened,
a housing into which the display foil together with the display foil carrier is retractable and out of which the display foil together with the display foil carrier is extendable,
at least one motorically drivable, length-variable actuator having a first end supported in and/or on the housing and a second end to which the upper end portion of the display foil carrier is attached, and
a guiding means in the housing for guiding the display foil and the display foil carrier in at least a partial area of their main portions along a line of curvature over less than 180 degrees or less than 135 degrees or less than 90 degrees during an extension and retraction of at least partial areas of the main portions of the display foil and the display foil carrier out of and into the housing by changing the length of the at least one actuator.
