An electronic device is provided. The electronic device includes a casing, a display module, and a communication module. The casing includes a first surface and a second surface. The display module is disposed on the first surface and has a display region. The communication module includes a first antenna module and a second antenna module. The first antenna module is disposed close to the display module and is corresponding perpendicularly to at least one part of the display region. The second antenna module is disposed close to the second surface. The communication module selectively receives and transmits a wireless signal along an outward direction extending from the first surface via the first antenna module or along an outward direction extending from the second surface via the second antenna module.
