Abstract: A notebook computer includes a host, a supporting frame and a display portion. The supporting frame is pivotally connected with the host and comprising a sliding slot. The display portion has a sliding member, which is pivotally connected with the supporting frame and slidably connected with the sliding slot, wherein the sliding member comprises a through hole. The signal cable is led through the through hole and extended within the supporting frame to electrically couple the display portion and the host. The signal cable comprises a bendable section. The signal cable is moved substantially along a plane by adjusting a bent angle of the bendable section when the display portion is slid along the sliding slot.
