Abstract: An expandable display apparatus comprises a main display unit and first and second expandable display panels. The main unit is defined as having a centerline axis. The main unit includes a pair of side walls oriented substantially along and disposed on opposite sides of the centerline axis. One or both of the side walls may include a display panel. The main unit contains first and second end openings oriented substantially across the centerline axis and disposed in opposing spaced-apart relation. The end openings communicate with a storage space between the pair of side walls. The display panels are removably stored side-by-side in the storage space and are movable in opposite directions through the end openings. The panels are movable along respective paths between respective stored positions inside the storage space and respective extended positions outside the storage space. The display panels align with the centerline axis of the main unit when the panels are in the extended position.
