A user interface display device and method are provided. The apparatus includes a process history storage unit for storing path information of a displayed user interface window, a user interface unit for displaying one or more second user interface windows, and a control unit for outputting a multiple-up instruction signal instructing the user interface unit to display a user interface window corresponding to the stored path information. The first user interface window is a current user interface window, and the second user interface windows are previously displayed user interface windows at a higher level than the first user interface window. Therefore, it is possible for a user to visualize the path of the user interface windows switched through to reach the current user interface window. Further, complicated keystrokes for switching from the lower level user interface window to the user interface window desired by the user are not required.
