The extending and retracting of the bendable display is facilitated by a first assembly on which a substantially planar visible portion of the display is disposed and a second assembly slidably attached to the first assembly. A space is defined by the first and second assemblies in which a bent portion of the display is housed. When the first assembly is extended (e.g., opened) with respect to the second assembly, at least a portion of the bent portion of the display is extended so as to be visible, and when the first assembly is closed (e.g., retracted) with respect to the second assembly, the extended bent portion of the display is retracted into the space between the first assembly and the second assembly, and is no longer visible. Various constructions of the first and second assemblies and corresponding structures are provided.
