Abstract
When supply of power has stopped, voltages of GDM signals are set as follows. A clear signal that contributes to removal of charge at floating nodes (an output control node and a stabilization node) in each unit circuit included in a shift register is set to a voltage of ground, and other signals (a gate start pulse signal, gate clock signals, and a reference voltage) are set to a gate-on voltage. To implement such settings, a single power supply system configuration that uses a voltage of only one channel as a scanning line selection voltage is adopted.
