Beschreibung
Zusammenfassung:	The luminance of light emitting elements varies when the characteristics thereof change due to changes in environment temperature and changes with time. It is an object of the present invention to suppress the effect of the change in current value of a light emitting element due to the changes of environment temperature and changes with time. The invention provides a display device provided with a compensation function for the changes in environment temperature and a compensation function for the change with time. The display device of the invention includes a light emitting element, a driving transistor connected to the light emitting element, and a monitoring light emitting element. By using this monitoring light emitting element, an effect of the change of current value of the light emitting element due to the change of environment temperature and change with time can be suppressed.
