Patent ID: 7522242

Claim:
An LCD device comprising: an LCD panel having at least one pixel that includes a first colored sub pixel and a second white sub pixel, wherein liquid crystal molecules of the second white sub pixel are aligned differently from liquid crystal molecules of the first colored sub pixel, wherein the first colored sub pixel has liquid crystal molecules vertically aligned in the voltage off-state and aligned in other directions except a direction substantially parallel to an absorption axis of at least one polarizing sheet in the voltage on-state, and the second white sub pixel has liquid crystal molecules vertical in the voltage off-state and aligned between about 0° and 3° with respect to the absorption axis of the polarizing sheet in the voltage on-state, if the LCD panel is a VA mode, or wherein the first colored sub pixel has liquid crystal molecules aligned in accordance with an electric field in the voltage on-state and twisted according to a polarizing sheet in the voltage off-state, and the second white sub pixel has liquid crystal molecules aligned in accordance with the electric field and aligned between 0° and 6° with respect to the absorption axis of the polarizing sheet in the voltage on-state and homogeneously aligned in the voltage off-state, if the LCD panel is a TN mode.
