A supporting apparatus for suspending two displays includes: a base seat unit including a fixing bracket and a pillar that is connected to the fixing bracket; two suspending arms, each having a first end portion that is movably connected to the pillar unit such that each of the suspending arms is movable along the pillar, and a second end portion that is opposite to the first end portion; two slide track units respectively connected to the second end portions of the suspending arms; and two display-supporting bracket units movably connected to the slide track units for mounting the displays. Through operation of the suspending arms, the sliding track units and the display-supporting bracket units, the displays can be moved to juxtapose and contact each other.
