A folding display frame comprises a grid of horizontal and vertical rod members forming an array of three dimensional cubicles. The cubicles have eight corners with a separate hub at each corner of the cubicle. The framework forming each cubicle has a top frame section, a bottom frame section, and two side frame sections. Each frame section is formed by two rods intersecting and pivotally join to each other midway between their ends. The ends of the rods in each cubicle are pivotally attached to corresponding hubs located at each of the corners of the cubicle. Adjacent cubicles in the array share common rods and hubs. Separate diagonal stabilizing members are located within bottom cubicles of the display frame to prevent the cubicles from being distorted into a parallelogram shape when the frame is erected in its fixed position and weight is supported on the front of the frame. Each diagonal stabilizing member comprises a telescoping brace comprised of inner and outer rod members slidable relative to each other to adjust the length of the brace. The rod members have means for restricting their maximum length, and the diagonal braces are mounted within the bottom cubicles so that they act as a restraint in the tension direction to restrict the bottom cubicles from distorting into a parallelogram shape.
