Display device including a unitary, rigid sheet defining a left center panel, a right center panel pivotally connected to the left center panels, a left side panel pivotally connected to the left center panel and a right side panel pivotally connected to the right center panel. Vertically extending separation lines are formed on a rear planar layer without penetrating or cutting a front planar layer so that the panels are able to pivot about vertical axes. Fold lines may be formed opposite the separation lines on the front planar layer to facilitate folding the sheet whereby the fold lines define the vertical axes about which the panels pivot. Folding of the sheet provides a compact configuration which enables the display device to be easily carried.
