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： When a light-emitting element having an intermediate conductive layer between a plurality of light-emitting layers is formed, the intermediate conductive layer can have transparency; and thus, materials are largely limited and the manufacturing process of an element becomes complicated by a conventional method.

Therefore, the present invention can provide a light-emitting element typified by an organic EL element in which a range of choice of materials that can be used as the intermediate conductive layer is broadened extremely, and which can realize a high light-emitting efficiency, a low power consumption and a high reliability, and further a display device using the light-emitting element.
