Abstract:
1. A liquid crystal display device comprising: a first switching element for supplying a data voltage supplied from a data line to a pixel electrode in response to a first scan signal applied to a first gate line during a first period; a second switching element for supplying a common voltage supplied from a common line to an auxiliary electrode in response to the first scan signal during the first period; a third switching element for supplying the data voltage supplied from the data line to the auxiliary electrode in response to a second scan signal applied to a second gate line during a second period subsequent to the first period; a common electrode to which the common voltage from the common line is applied; a liquid crystal capacitor coupled between the pixel electrode and the common electrode; and a first storage capacitor coupled between the pixel electrode and the auxiliary electrode, wherein a voltage at the auxiliary electrode changes from the common voltage during the first period to the data voltage during the second period, and a voltage at the pixel electrode changes from the data voltage during the first period to an amplified data voltage higher than the data voltage during the second period in accordance with a capacitance ratio between the liquid crystal capacitor and the first storage capacitor.
