Abstract: In a pulse output circuit in a shift register, a power source line which is connected to a transistor in an output portion connected to a pulse output circuit at the next stage is set to a low-potential drive voltage, and a power source line which is connected to a transistor in an output portion connected to a scan signal line is set to a variable potential drive voltage. The variable potential drive voltage is the low-potential drive voltage in a normal mode, and can be either a high-potential drive voltage or the low-potential drive voltage in a batch mode. In the batch mode, display scan signals can be output to a plurality of scan signal lines at the same timing in a batch.

Abstract: It is an object of the present invention to prevent an insulating film from peeling in a section where the insulating film is adjacent to a sealing region. Over a first substrate 104, a pixel portion 100 provided with a light emitting element, a source driver 101, a gate driver 102, and a sealing region 103 are provided. A light emitting element is sealed between the first substrate 104 and a second substrate 110 by a sealant 108. An insulating film 107 serves as a partition wall of the light emitting element. An end portion of the insulating film 107 which is adjacent to the sealing region 103 does not overlap with a step formed by a side surface and an upper surface of a conductive film 106 which serves as a wiring.
