A portable electric device, to provide mobile phones and PDA functions, includes a main body and a sub-body. The main body has a first keyboard and a second keyboard that are operated in different directions. The sub-body has a large display screen on one side and a small display screen on the other side. The sub-body is pivotally coupled on one side of the main body, corresponding to a QWERTY keyboard through a biaxial hinge. The sub-body may be selectively having a large display screen or a small display screen, folding over the main body, to cover the QWERTY keyboard, or to be lifted, to form an angle with the main body, to provide different operation modes for the mobile phone or PDA functions.
