Abstract
A liquid crystal display includes a first substrate on which a first sub-pixel electrode and a second sub-pixel electrode are spaced apart from each other in a first direction, different voltages being applied to the first sub-pixel electrode and the second sub-pixel electrode, a first switching element which controls a voltage applied to the first sub-pixel electrode, a second switching element which controls a voltage applied to the second sub-pixel electrode, a variable resistor which drops an output voltage of the second switching element and apply the dropped output voltage to the second sub-pixel electrode, a second substrate on which a common electrode is disposed, and a liquid crystal layer disposed between the first substrate and the second substrate.
