PURPOSE: A combination PDA and display device of an IP phone is provided to display necessary information without increasing the cost. CONSTITUTION: An IP(Internet Protocol) phone(10) and a PDA(Personal Digital Assistant)(20) are normally separated. In the case that the IP phone(10) needs a display device, the PDA(20) is mounted at a combining part formed at an upper part of one side of the IP phone(10) to use a touch screen(20A) of the PDA(20). To attach or detach the PDA(20) to or from the IP phone(10), the PDA(20) includes an LCD(Liquid Crystal Display) multiplexer(26A), a touch screen multiplexer(27A), and a connector(25). Signal lines and power lines of the IP phone(10) and the PDA(20) are combined with each other through connectors(15,25).
