Zusammenfassung:The brightness of a light emitting element varies when changes in ambient temperature or changes with time occur. In view of this, the invention provides a display device where the influence of variations in the current value of the light emitting element due to changes in ambient temperature and changes with time can be suppressed. The display device of the invention includes a monitoring element that is driven with a constant current, and a voltage applied to the monitoring element is detected and inputted to a light emitting element. In other words, the monitoring element is driven with a low current, and a voltage applied to the monitoring element is inputted to the light emitting element such that the light emitting element is driven with a constant current.
