A portable display stand for removable attachment of fixtures for the display of merchandise is disclosed. The display stand features a hinged vertical support panel sub-assembly, including top and bottom panel segments, to reduce size and promote portability. Slideable pin locks within top or bottom braces for the top and bottom panel segments slide out from a disengaged position and lock in the engaged position, stabilizing the top and bottom panel segments relative to each other, for assembly. The hinged connection between the braces for the top and bottom panel segments promotes fast alignment during assembly. Assembly of the vertical support panel sub-assembly and the first and second leg sub-assemblies occurs without tools. The display stand disassembles into three (maximum) portable sub-assemblies that may be transported in a carrying case, and may be reassembled without tools in less than a minute.
