SUMMARY OF THE INVENTION An object of the present invention is to provide a new light emitting device having a low initial deterioration, and to provide a display device in which the initial deterioration is reduced by a new driving method for a display device having the light emitting element and the change in deterioration with time is reduced. It is. One feature of the present invention is light emission having a first electrode, a second electrode provided to face the first electrode, and a layer in which a metal oxide and an organic compound interposed between the first electrode and the second electrode are mixed. An aging drive is performed for the display device provided with the element.n n n n Display device, light emitting element, deterioration with time, electrode, aging |
