A portable electronic device includes a main body including a housing, a display electrically connected to the main body, and a frame for connecting between the main body and the display. The display includes a display panel and a carrier for carrying the display panel. The portable electronic device is capable of being operated to switch between a closed state and an open state. When the portable electronic device is in the closed state, the display covers the main body with either one of the display panel or the carrier facing the housing of the main body, and the main body and the display are surrounded by the frame. When the portable electronic device is in the open state, the main body is straddled by the frame and is supported by the frame to define a first predetermined angle between the main body and the frame.
