In an adjustable supporting device, a tubular coupling member is disposed uprightly on a supporting base. A movable frame member is movably extended into the coupling member, is in friction engagement with the coupling member, and includes a frame body coupled to a display panel and formed with a passage groove communicated with a receiving space. A biasing member has a straight coupling portion passing through the passage groove and coupled to the coupling member, and a spiral portion having an axis, connected to the coupling portion, and disposed in the receiving space. The movable frame member further includes an axial rod extending through the spiral portion along the axis and engaging the frame body such that the spiral portion of the biasing member is positioned in the receiving space.
