摘要： A light emitting device that achieves long life, and which is capable of performing high duty drive, by suppressing initial light emitting element deterioration is provided. Reverse bias application to an EL element (109) is performed one row at a time by forming a reverse bias electric power source line (112) and a reverse bias TFT (108). Reverse bias application can therefore be performed in synchronous with operations for write-in of an image signal, light emission, erasure, and the like. Reverse bias application therefore becomes possible while maintaining a duty equivalent to that of a conventional driving method.

摘要翻译： 提供了通过抑制初始发光元件劣化而实现长寿命并能够进行高占空比驱动的发光器件。 通过形成反向偏置电源线（112）和反向偏压TFT（108），一次对一个EL元件（109）施加反向偏置。 因此，可以与图像信号的写入，发光，擦除等的操作同步地执行反向偏置应用。 因此，在保持与常规驱动方法相同的占空比的情况下，可以实现反向偏置应用。

摘要： The reliability of an EL element is enhanced while the increase of the electric power consumption is suppressed. It becomes possible that in a SES drive, the reverse bias is applied to the EL element driven at a constant electric current. Moreover, the application of the reverse bias is performed by varying only the counter electrode, and thus withstand voltage of TFT and the increase of the electric power consumption due to the increase of voltage of the gate signal line drive circuit, which becomes a problem when changing greatly the electric current supplying line, can be suppressed. Furthermore, the reduction of the electric power consumption can also be achieved while the enhancement of the reliability is secured by making the reverse bias smaller than the forward bias. Moreover, the increase of the number of electric sources can be also suppressed by making the potential be in common with the potential of the electric source of the source signal line drive circuit or the gate signal line drive circuit, at the time when the reverse bias is applied.
