It is an object of the present invention to provide a display support apparatus that has a simple structure and can be stored in a small storage space. The display support apparatus includes a main leg 11 that extends downward from a rear face portion of a display, and has a lower end portion provided with an auxiliary leg portion 12 extending forward in a horizontal direction, and a base member 6 that is pivotably coupled to the auxiliary leg portion 12 about a shaft 21. The base member 6 includes a coupling portion 32 that abuts against a bottom face of the auxiliary leg portion 12 in front of the shaft 21, an interlock portion 42 that forms interlocking so that the base member 6 is not pivoted in a state where the coupling portion 32 abuts against the bottom face of the auxiliary leg portion 12.
