Patent ID: 8487857

Claim:
A liquid crystal display (LCD) device, comprising: a data drive circuit that inverts polarities of data every 2k horizontal periods that are less than a frame interval for each frame (k is an integer not less than 2); and an LCD panel including a plurality of data lines and a plurality of gate lines crossing each other to define a plurality of effective pixels formed in an effective display area and a plurality of dummy pixels formed outside the effective display area, each of the effective and dummy pixels including a switching device, wherein the LCD panel further comprises first horizontal lines having the plurality of effective pixels, and second horizontal lines having the plurality of effective pixels and the plurality of dummy pixels, wherein first switching devices connected to the first horizontal lines and second switching devices connected to the second horizontal lines are arranged in a zigzag on the LCD panel, wherein source electrodes of the first switching devices connected to the first horizontal lines are connected to the data lines arranged on the left side of the first switching devices, wherein source electrodes of the second switching devices connected to the second horizontal lines are connected to the data lines arranged on the right side of the second switching devices.
