Abstract: A display device includes a display section, a touch panel, and a controller. The display section displays a first icon. The touch panel detects a first touch operation and a second touch operation different from the first touch operation to the first icon. The controller causes the display section to display a window associated with the first icon upon detection of either of the first and second touch operations. The controller controls the display section such that a window displayed upon detection of the second touch operation is different in size from a window displayed upon detection of the first touch operation.
