Abstract: Provided in the present application is a mobile terminal. The mobile terminal comprises two shells that are rotatably connected, and further comprises a flexible screen assembly covering the two shells, and an edge of the flexible screen assembly being connected to the two shells in an adhered manner. When the mobile terminal is folded, the flexible screen assembly is bent with the rotation of the two shells, but since the flexible screen assembly is a multi-layer structure, the flexible screen assembly becomes arched. For this reason, the flexible screen assembly is respectively connected to two groups of limiting members, and the two groups of limiting members are slidably connected to the two shells and are used for defining the relative vertical distance between the flexible screen assembly and the two shells. One end of the limiting members is fixedly connected to the flexible screen assembly, and the other end is slidably connected to the shell, thereby defining the vertical distance between the shell and the flexible screen assembly through the limiting members. Therefore, the arching of the flexible screen assembly when bent can be improved through the limiting members, and the effect of the mobile terminal during use is improved.
