In a display device, the display unit includes a first portion and a second portion. The display control unit changes a screen image to display from one to another of the plurality of screen images along a screen navigation path starting from the base screen image. The navigation string generating unit generates a navigation string including the title strings each corresponding to a screen image which is positioned in a part of the screen navigation path from the base screen image to a current screen image that is displayed on the first portion currently. The navigation string display unit controls the display unit to display the navigation string in the second portion. When the first determining unit determines that a title string is selected, the selected screen display unit controls the display unit to display a screen image specified by the selected title string in the first portion.
