In a terminal device, when application screens of a plurality of types of applications are being displayed individually and the display directions thereof differ from each other, a control section selects any one of the plurality of types of applications as a reference for display control, and orients the display direction of an application that is not the control reference to the display direction of an application that is the control reference. That is, when the display direction of an application displayed on one display section is changed from a vertical direction to a horizontal direction, the display direction of an application displayed on another display section is changed from the vertical direction to the horizontal direction so as to follow the foregoing change.
