摘要 |
A gate driver (24) which is provided by an IGZO-GDM and a level shifter circuit (13) are connected to each other via a first through a fifth wires (OL1 through OL5). Each wire (OL) is connected to a discharge unit (190). If an electric power supply to a first through a fifth output circuits (OC1 through OC5) in the level shifter circuit (13) becomes lower than a lower operation limit value during a power-off sequence which is supposed to remove a residual charge from inside a panel, outputs from the first through the fifth output circuits (OC1 through OC5) assume a high-impedance state, whereupon a potential on each wire (OL) is drawn by a discharge unit (190) into a ground potential. Therefore, residual charge inside the panel is removed quickly and stably when power supply is shut off. |
