This application provides a foldable display panel. A foldable portion in the foldable display panel includes a fixed mechanism and a rotary mechanism rotatably connected to the fixed mechanism. The rotary mechanism includes a first rotary mechanism and a second rotary mechanism. The first rotary mechanism is connected to a first flat portion. The second rotary mechanism is connected to a second flat portion. A heat dissipation member is connected to at least one of the first rotary mechanism and the second rotary mechanism. By means of this application, a risk of wear is reduced for the rotary mechanism.
