| 20100159785 | IN-PLANE SWITCHING MODE LIQUID CRYSTAL DISPLAY DEVICE - An IPS mode LCD device is disclosed in which a common voltage drop and delay is decreased. The LCD includes gate and data lines crossing each other to define pixel regions. Thin film transistors are formed at crossing portions of the gate and data lines. Common lines are parallel with the gate lines and common electrodes project from the common lines parallel with the data lines. Pixel electrodes connected with drain electrodes of the thin film transistors are formed in the pixel regions between the parallel common electrodes. A first common voltage supplying line applies a first common voltage or a second common voltage to a closed circuit formed by grouping the adjacent odd numbered common lines. A second common voltage supplying line applies the second common voltage or the first common voltage to a closed circuit formed by grouping the adjacent even numbered common lines. | 06-24-2010 |
| 20100277682 | LIQUID CRYSTAL DISPLAY DEVICE - A liquid crystal display device has pixel regions defined by gate lines and data lines perpendicular to the gate lines.
