Method for controlling liquid crystal display device, device for driving liquid crystal display device, liquid crystal display device, and electronic apparatus

A driving device for driving a liquid crystal display device that displays a desired image by controlling an amount of charge stored in a liquid crystal layer, the driving device comprising:

• a first transistor and second transistor;
• a detector that detects a turning-off of a power supply on which a liquid crystal display device operates;
• and
• a connection device that, upon detection of the turning-off of the power supply by said detector, connects said first transistor to a ground level, and connects the second transistor to a source voltage.

A liquid crystal display device that displays a desired image by controlling amounts of charge stored in liquid crystal layers, the liquid crystal display device comprising:

• a detector that detects a turning-off of a power supply on which a liquid crystal display device operates;
• a controller that provides an instruction to connect predetermined lines upon detection of the turning-off of the power supply by said detector;
• a first connector that connects at least one of the predetermined lines, in response to said instruction, to a ground level;
• and
• a second connector that, upon the detection of the turning-off of the power supply, connects another one of the predetermined lines to a source voltage to discharge current to the liquid crystal layer.

A liquid crystal display device comprising:

• a liquid crystal display panel having first substrate provided with a data line, a second substrate provided with a scanning line, and a plurality of pixels each having a series of connection of a non-linear element and a liquid crystal layer connected between said data line and said scanning line;
• a detecting circuit that detects a turning-off of a power supply on which the liquid crystal display device operates;
• and
• a switch circuit that connects, upon detection of the turning-off of the power supply by said detecting circuit, a first supplying line of a selection voltage to be applied onto said scanning line to a ground level, and connects a second supplying line of a selection voltage to a source voltage.
