摘要： In order to keep the luminance of a light emitting element constant, the correction is performed by an external device such as a computer, in which case a display device is inevitably complicated and increased in size. Even when degradation characteristics of the light emitting element are previously stored in a computer, the degradation characteristics vary at random depending on hysteresis of the light emitting element; therefore, changes in luminance cannot be corrected. According to the invention, a display device includes a displaying light emitting element provided in a display portion and a plurality of monitoring light emitting elements having the similar characteristics as the displaying light emitting element. At least one of the monitoring light emitting elements is operated under a condition different from the displaying light emitting element, and the ratio of the total amount of charge flowing through the displaying light emitting element to that flowing through the monitoring light emitting element is controlled to satisfy a certain relation in view of luminance degradation. When the one monitoring light emitting element reaches a predetermined voltage or time, the connection is switched from the one monitoring light emitting element to another monitoring light emitting element that has been operated under the same condition as the displaying light emitting element.

摘要： It is an object of the present invention to provide a light emitting element with a low driving voltage. In a light emitting element, a first electrode; and a first composite layer, a second composite layer, a light emitting layer, an electron transporting layer, an electron injecting layer, and a second electrode, which are stacked over the first electrode, are included. The first composite layer and the second composite layer each include metal oxide and an organic compound. A concentration of metal oxide in the first composite layer is higher than a concentration of metal oxide in the second composite layer, whereby a light emitting element with a low driving voltage can be obtained. Further, the composite layer is not limited to a two-layer structure. A multi-layer structure can be employed. However, a concentration of metal oxide in the composite layer is gradually higher from the light emitting layer to first electrode side.
