Driving method of liquid crystal display device

A driving method of a liquid crystal display device using an OCB cell, characterized by the steps of:

• applying voltage pulses between a storage capacitance electrode of a TFT and a common electrode prior to a start of a display operation, said voltage pulses generated at a frequency lower than that of corresponding voltage pulses when applying a voltage for said display operation;
• causing each pixel to have bend orientation by a strong electric field that is generated between the electrode of the TFT and the common electrode;
• and
• applying, at the same time, a voltage that is higher then that to generate an electric field necessary to maintain bend orientation between a display electrode and the common electrode, to thereby effect transfer to bend orientation in short time.

A driving method of a liquid crystal display device using an OCB cell, characterized by the steps of:

• controlling gate on/off periods of a TFT at a given time interval before a display operation, each period being longer than a corresponding gate on/off period when applying a voltage for said display operation;
• causing each pixel to have bend orientation by a strong electric field that is generated between a gate electrode of the TFT and a common electrode;
• and
• applying, at the same time, a voltage that is higher than that to generate an electric field necessary to maintain bend orientation between a display electrode and the common electrode, to thereby effect transfer to bend orientation in short time.
