PURPOSE: To provide a liquid crystal display device capable of reducing a power consumption in the non-display state, and capable of shortening a transition time of state transition from the display state to the non-display state. CONSTITUTION: This liquid crystal display device has a liquid crystal display panel 9, common and segment drivers 6, 3 for driving each pixel thereof, common and segment driver control circuits 5, 2 for controlling the drivers 6, 3 based on a display timing, a booster circuit 7 for outputting a power source of plural potentials including a grounding potential, a common power source selector 4 connected to the middle between the circuit 7 and the common driver 6, for selecting and supplying thereto two power sources on the high potential side and the low potential side, a segment power source selector 1 connected to the middle between the circuit 7 and the segment drivers 3, for selecting and supplying thereto two power sources on the high potential side and the low potential side, and a means for inputting a non-display control signal into the common power source selector 4, the common driver control circuits 5, the segment power source selector 1 and the segment driver control circuits 2 at the non-display time of the pixels, and for outputting the grounding potential from the common and segment drivers 6, 3.
