An electronic device and a manufacturing method thereof are disclosed in the present disclosure. The electronic device comprises a first flexible substrate, a second flexible substrate and a sealing material. The first flexible substrate comprises a first laser-cutting buffer region, and the first flexible substrate comprises a first edge. The second flexible substrate comprises a second laser-cutting buffer region, and the second flexible substrate comprises a second edge. The sealing material is disposed between the first flexible substrate and the second flexible substrate. The sealing material is away from the first edge by the first laser-cutting buffer region and the sealing material is away from the second edge by the second laser-cutting buffer region. Therefore, the cracking of the sealing material can be reduced.
