Abstract
The invention provides a liquid crystal display device that includes an IGZO-GDM which can quickly remove a residual charge in a panel when the power supply is turned off, and a driving method of the liquid crystal display device. Each bistable circuit that configures a shift register includes a thin film transistor TI for increasing a potential of an output terminal based on a first clock, a region netA connected to a gate terminal of the thin film transistor TI, a thin film transistor TC for lowering a potential of the region netA, and a region netB connected to a gate terminal of the thin film transistor TC. In such a configuration, a power supply off sequence includes a display off sequence and a gate off sequence. The gate off sequence includes at least a gate-bus-line discharge step (tto t), a netB discharge step (tto t), and a netA discharge step (tto t).
