1. A display device, comprising:
a first display portion configured to display a first gauge that, with regard to an electric mileage difference between a specific electric mileage and a reference electric mileage, change in accordance with change in a cumulative value in which the electric mileage difference at one or more of a particular timing is accumulated;
a second display portion configured to display an estimated cruising range of a vehicle; and
a memory and processor programmed to:
calculate the specific electric mileage as an instantaneous electric mileage calculated based on a set interval previous to a current point in time;
calculate the reference electric mileage by dividing a traveling distance from a time a power of the vehicle has been switched from off to on to the current point in time, divided by a cumulative electric power consumed by the vehicle from the time the power of the vehicle being has been switched from off to on to the current point in time;
acquire the estimated cruising range obtained using remaining charge of a battery that supplies electric power to a traction motor of the vehicle;
change the first gauge of the first display portion, such that only when the cumulative value is equal to or more than a predetermined value, display, in the second display portion, information indicating increasing the estimated cruising range displayed in the second display portion.
