The display apparatus 2 comprises a cascading display device 4 which defines three elongate channels 6, 8, 10 in which articles, for example magazines or newspapers, may be arranged and displayed. The display device 4 is supported by a support device 12 which extends between a rear wall 14, situated behind the device 4, and the display device and is arranged to support the display device against downwards movement. The support device includes a support flange 78 which extends into a gap defined between limbs 34, 36 of respective channels 6, 8. Support rods 16 extend between the wall 14 and the display device 4 and are arranged to space the display device 4 from the wall 14; to prevent the display device 4 from pivoting about the support device 12; and to add rigidity to the display apparatus. In another embodiment, a support device is provided which includes support flanges which extend into respective gaps defined between the first and second channels 6, 8 and the second and third channels 8, 10.
