A flexible electronic device includes a first flexible substrate, a first electronic component, a second flexible substrate, a second electronic component and an adhesive layer disposed between the first flexible substrate and the second flexible substrate. The first electronic component is disposed on a first surface of the first flexible substrate. The second electronic component is disposed on a first surface of the second flexible substrate. The first surface of the first flexible substrate has a first FPC bonding area having an orthogonal projection projected on a plane where the second flexible substrate is located does not overlap the second flexible substrate. The first surface of the second flexible substrate has a second FPC bonding area having an orthogonal projection projected on a plane where the first flexible substrate is located does not overlap the first flexible substrate.
