Patent 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.
