A portable electronic device includes a base, a first display pivotally connected to the base, a second display, and a linkage mechanism. The first display is movable to be opened or closed relative to the base. The second display is located between the base and the first display. The linkage mechanism includes at least one first link. Two ends of the first link are pivotally connected to the first display and the second display, respectively. When the first display is opened relative to the base, the at least one first link rotates to drive the second display to move up relative to the base. When the first display is closed relative to the base, the at least one first link rotates in an opposite direction to drive the second display to move down to be accommodated between the first display and the base.
