An information processing device includes: a foldable one display; a memory which stores at least a program; and a processor which executes the program stored in the memory. By executing the program stored in the memory, the processor performs: operating state switching processing to switch an operating state of a system among a first operating state, a second operating state in which processing of the system is more limited than that in the first operating state and at least the display is hidden, and a third operating state in which the processing of the system is shut down, display mode switching processing to switch between a first display mode to control display by setting a screen area of the display as one display area, and a second display mode to control display by splitting the screen area into plural display areas, and setting switching processing.
