An electronic device includes a first body, a second body and at least one driving mechanism. The second body includes a casing and a flexible screen installed on the casing. The driving mechanism includes a shaft, a driving element and a linking assembly. The shaft has first and second connecting portions opposite to each other, the first connecting portion is fixed to the first body, and the second body is pivoted to the second connecting portion. The driving element is sleeved on the shaft and is located in the casing. The linking assembly is carried by the casing and covered by the flexible screen. When the second body is folded onto the first body, the flexible screen keeps flat. When the second body is unfolded with respect to the first body, the driving element is rotated and moved with respect to the shaft to drive the linking assembly to move, and the linking assembly drives the flexible screen to bend.
