Patent ID: 8581819

Claim:
A liquid crystal display device, comprising: first and second substrates facing each other with a liquid crystal layer therebetween; a first data line, a second data line, a gate line, a pixel electrode, and a reset electrode being formed on the first substrate, the first data line crossing the gate line to define a pixel region; a common electrode being formed on the second substrate; a first switching element electrically connected to the gate line and the pixel electrode; and a second switching element electrically connected to the gate line and the reset electrode, wherein during a first period of a frame, the pixel electrode and the reset electrode are configured to generate a horizontal electric field with respect to the substrates to display images; wherein, during a second period of the frame, a reset voltage is applied to the reset electrode by the second data line in order to generate a vertical field with respect to the substrates to restore the liquid crystal molecules, wherein, an additional gate signal is applied to the first and second switching elements, in synchronization with the additional gate signal, the reset voltage is applied to the reset electrode and a data signal is applied to the pixel electrode, wherein, a voltage of a same level is applied to the pixel and reset electrodes, and a different voltage is applied to the common electrode, thereby forming the vertical electric field; wherein the first period and the second period are different periods from each other, and wherein the reset electrode is formed for each block comprising a plurality of pixels.
