PROBLEM TO BE SOLVED: To provide a display device where fluctuation of current values of a light-emitting element caused by the ambient temperature change and degradation with time is suppressed.

SOLUTION: A monitoring element 102 driven with a constant current is provided. After detecting a voltage generated in the monitoring element 102, the voltage is applied to a light-emitting element. That is, the monitoring element is driven with the constant current, and the voltage in the monitoring element 102 is applied to the light-emitting element so that the light-emitting is driven with the constant voltage. When a predetermined condition is satisfied, the voltage generated in the monitoring element 102 are sampled and a voltage is supplied to the light emitting element 115 from an extrapolation power supply circuit which generates the voltage based upon a mathematical formula of a change from the sampled voltage.
