Patent ID: 8766888

Claim:
An IPS mode LCD device comprising: first and second substrates; N gate lines arranged on the first substrate substantially in parallel and the N gate lines sequentially applied with a scan signal from a gate driver; M data lines arranged to cross the gate lines so as to define m×n pixel regions; a plurality of first switching devices formed at each crossing of the gate lines and the data lines; first electrodes electrically connected to the first switching devices; second electrodes electrically connected to a plurality of second switching devices, each pixel region including one of the first electrodes and one of the second electrodes that generate a horizontal electric field; a common voltage supplier in each pixel region that generates a common voltage from voltages applied to a n−1th gate line and a nth gate line and supplies the generated common voltage to one of the second electrodes through one of the second switching devices, wherein control terminals of both one of the first switching devices and one of the second switching devices in each pixel region are electrically connected to the nth gate line; and a liquid crystal layer between the first and second substrates.
