Patent ID: 8587580

Claim:
A liquid crystal display device comprising: a liquid crystal display panel including a plurality of scan lines, a plurality of odd and even column data lines, and a plurality of pixels connected to the scan lines and the data lines, the pixels being arranged in a matrix form; a control signal generating unit for providing a write control signal and a reset signal to the pixels of the liquid crystal display panel, respectively; a common voltage generating unit for providing a common voltage to each of the pixels; and a boosting voltage generating unit for providing boosting voltages to the pixels such that only the pixels connected to an odd column data lines each receive a first boosting voltage and only the pixels connected to an even column data lines receive a second boosting voltage different from the first boosting voltage, each of the pixels comprising: a first thin film transistor having a gate electrode connected to one of scan lines and a source electrode connected to one of the data lines; a second thin film transistor having a source electrode connected to a drain electrode of the first thin film transistor and a gate electrode connected to a write control signal line providing the write control signal; a third thin film transistor having a source electrode connected to a drain electrode of the second thin film transistor and a gate electrode connected to a reset control signal line providing the reset signal; a storage capacitor provided between the drain electrode of the first thin film transistor and the common voltage generating unit; a liquid crystal capacitor having a first electrode connected to the drain electrode of the second thin film transistor; and a boosting capacitor having a first electrode connected to the source electrode of the third thin film transistor and a second electrode connected to a drain electrode of the third thin film transistor.
