Abstract
A liquid crystal display device is provided, which may reduce flicker in all display gray levels. The liquid crystal display device includes a scan line drive circuit, a signal line drive circuit and a common connection line drive circuit. The common connection line drive circuit applies a voltage, the voltage having polarity opposite to polarity of the signal line, to a common connection line corresponding to a liquid crystal element as a selection object in a write period for writing into the liquid crystal element as a selection object, and applies one or multiple voltages, each voltage having a value different from a center value between an upper limit value and a lower limit value of voltages applied to the common connection lines in the write period, to the common connection lines in a holding period after writing into the liquid crystal element as a selection object is performed.
