Disclosed is a display case assembly made of papers because people are reluctant to use an existing display case because of environmental pollution. The display case according to the present invention comprises: top and bottom plates which are formed of the papers to form the ceiling and the bottom surfaces of the display case, and which have fitting plates protruding from the three surfaces of the top and bottom plates except the front surface thereof; left and right plates which are formed by folding a paper as a box shape with opened top and bottom, and which insert and couple the opened top and bottom to the left and right fitting plates of the top and bottom plates so as to form the left and right walls of the display case; and a rear plate which is formed by folding a paper as the box shape with opened top and bottom, and which inserts and couples the opened top and bottom of the rear plate to the rear fitting plates of the top and bottom plates. The inner surfaces, facing each other, of the left and right walls have an insertion groove, respectively, to insert both ends of reinforcing plates. Cutting grooves are formed in both ends of the reinforcing plates to be fitted in the plates forming the inlet of the insertion grooves, thereby preventing the deformation of the display case by preventing the left and right plates from being opened or retracted. The present invention contains a stair-type display case having at least two-stepped stairs which has a fitting protrusion formed on the bottom surface thereof to fit in the opened tops of the left and right walls, thereby additionally expanding the display case. |
