PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of accelerating an alignment speed and to provide its driving method. SOLUTION: The liquid crystal display device includes a liquid crystal display panel and a power supply section. The liquid crystal display panel has an alignment interval during which liquid crystal molecules are transferred from a splay state to a bend state and a normal operating interval during which an image is displayed in the bend state. The liquid crystal display panel includes a first substrate having a storage electrode and a pixel electrode to which data voltage is applied, a second substrate having a common electrode, and a lliquid crystal layer interposed between the first and second substrates. The power supply section supplies a first alignment voltage that is higher than the data voltage to the common electrode and supplies a second alignment voltage that is lower than the data voltage to the storage electrode, during the alignment interval. Thus, a transition speed from a splay state into a bend state is enhanced, so that an alignment interval may be decreased. COPYRIGHT: (C)2008,JPO&INPIT
