A portable display device (1) includes a non-volatile display portion (21) configured to display information even when power from a power source is turned off, and a controller (10) configured to drive the display portion (21) to display information in the display portion (21). The controller (10) is configured to replace information displayed in the display portion (21) with another information, which is different from the information displayed in the display portion (21), by turning power on repeatedly at a predetermined timing in a state of power-off. |
