Abstract: In a first transition period during which an operation mode transitions from a normal mode to a low power consumption mode, a source driver changes the potential of each source bus line to 0 V, a gate driver sets all gate bus lines to be in a high impedance state in a state where a gate low power source voltage VGL (a potential of a second level: for example, −7 V) is applied to all of the gate bus lines, and a power source IC sets a common electrode and a VGL line to be in a high impedance state.
