A display apparatus includes a rendering unit, a priority determination unit, and a synthesized screen generation unit. The rendering unit determines necessary virtual screens based on an instruction signal from a navigation unit and information processing units. The priority determination unit determines a display priority based on a display content with respect to each virtual screen. The synthesized screen generation unit generates a synthesized screen to be displayed, by overlapping the determined virtual screens based on the determined display priorities. In this configuration, a certain window in a virtual screen, which has been displayed second or later in the order of overlapping windows, may be newly assigned the highest display priority when a display content in the certain window is changed. This allows the certain window to be displayed topmost and easily viewed by a user.
