    摘要： A display device capable of applying reverse driving voltage for a light emitting element to a light emitting element every certain period for prolonging light emitting element's life and burning out a shorted portion. Besides a path for supplying forward current to the light emitting element, a path for supplying reverse current is provided. A driving transistor is provided in the former path while a transistor (AC transistor) is provided in the latter path, thereby a switching between the two paths is controlled. The AC transistor has a rate L/W of a channel length L to a channel width W smaller than that of the driving transistor. Accordingly, current flowing into the light emitting element can be flowed into the AC transistor in the case of reverse driving voltage being applied to the light emitting element.

    摘要翻译： 一种显示装置，其能够每隔一定时间向发光元件施加反向驱动电压，以延长发光元件的使用寿命并烧毁短路部分。 除了用于向发光元件供给正向电流的路径之外，还提供了用于提供反向电流的路径。 在前一路径中提供驱动晶体管，而在后一路径中提供晶体管（AC晶体管），由此控制两条路径之间的切换。 AC晶体管的通道长度L的通道宽度W的比率L / W小于驱动晶体管的通道宽度W. 因此，在将反向驱动电压施加到发光元件的情况下，流入发光元件的电流可以流入AC晶体管。

    摘要： A light emitting device which is able to suppress power consumption while a balance of white light is maintained is provided. According to the present invention, either the potential level of the Hi video signal or Lo video signal which is given to a gate electrode of a transistor, and the potential level of the power source lines are changed by the respective corresponding colors. Concretely, the potential level at the side of Lo and the potential level of the power source line are made to be changed by the respective corresponding colors when a transistor which controls current supplied to a light emitting element is a p-channel type. Conversely, the potential level at the side so of the Hi and potential level of the power source line are made to be changed by the respective corresponding colors when a transistor which controls current supplied to a light emitting element is an n-channel type.

    摘要： The invention provides a light emitting device which is capable of displaying on both sides, has a small volume, and is capable of being used as a module. A light emitting element represented by an EL element and the like is used in a pixel portion, and two pixel portions are provided in one light emitting device. A first pixel portion has a structure to emit light only from a counter electrode side of the light emitting element. A second pixel portion has a structure to emit light only from a pixel electrode side of the light emitting element. That is, in the first pixel portion and the second pixel portion, directions of light emission are reverse in front and back.
