Abstract
A display device includes gate lines; data lines; charge control lines each including a charge control voltage input pad; first and second thin film transistors (TFTs) each including control and input electrodes connected to the gate and data lines, respectively; a first liquid crystal capacitor connected to an output electrode of the first TFT; a second liquid crystal capacitor connected to an output electrode of the second TFT; a charge control TFT including a control electrode and an input electrode connected to one of the charge control lines and the second pixel electrode, respectively; and a charge-down capacitor connected to an output electrode of the charge control TFT. A duration time of a turn-on voltage pulse applied to the charge control TFT is different from a duration time of a turn-on voltage pulse applied to the first TFT transistor or the second TFT.
