Abstract:
An LCD(Liquid Crystal Display) is provided to implement a narrow viewing angle mode by achieving switching between a wide viewing angle mode and the narrow viewing angle mode if a privacy protecting function is requested. A first common electrode(270a) is formed on a first substrate(110), and applied with first common voltage. A second substrate(210) faces the first substrate. A first pixel electrode(191a) is formed on the second substrate, and applied with first data voltage having first polarity with respect to the first common voltage. A second pixel electrode(191b) is spaced from the first pixel electrode at predetermined intervals on the second substrate, and applied with second data voltage having second polarity with respect to the first common voltage. A second common electrode(270b) is formed on the first substrate, and spaced from the first common electrode as much as a predetermined distance. A third pixel electrode(191c) is formed on a second substrate facing the second common electrode, and spaced from the first and second pixel electrodes as much as a predetermined distance. A first LC layer(3) is inserted between the second substrate and the first substrate where the first common electrode is formed. A second LC layer(30) is inserted between the second substrate and the first substrate where the second common electrode is formed. In the first substrate where the first common electrode is formed, a white color filter is formed. In the second substrate where the second common electrode is formed, RGB(Red, Green and Blue) color filters are formed. If a wide viewing angle is necessary, a signal controller applies no voltage to a sub pixel. Therefore, an LC layer of a sub pixel area is arranged in parallel to an LC layer of a main pixel area. If a narrow viewing angle is necessary, the signal controller applies voltage to the sub pixel. Therefore, the LC layer of the sub pixel area is arranged to be vertical to the LC layer of the main pixel area. The dielectric constant of the first and second LC layers has an anisotropic characteristic.
