A flexible electronic device includes: a base; a supporting plate having a first end pivotally connected to the base, and a second end; two pivot modules disposed at the second end; a bearing frame having a fixed part connected to the two pivot modules, and two curved parts connected to the fixed part; a bending mechanism disposed on the fixed part and the two curved parts and connected to the pivot modules; and a flexible panel disposed on the bearing frame and covering the bending mechanism. When the flexible electronic device is switched to a curve mode, the bending module drives the two curved parts to stretch with respect to the fixed part to bend the flexible panel. When the flexible electronic device is switched to a flat mode, the bending module drives the two curved parts to move close to the fixed part to flatten the flexible panel.
