  • Patent number: 8077127
    Abstract: An LCD device includes an LCD panel and a power supply section. The LCD panel includes a first substrate having a storage electrode and a pixel electrode, a second substrate having a common electrode, and a liquid crystal layer interposed between the first and second substrates. The LCD panel has an alignment interval during which liquid crystal molecules are transitioned from a splay state to a bend state and a normal operating interval during which an image is displayed in the bend state. 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 transient splay state into a bend state is enhanced, so that an alignment interval may be decreased.
