Patent ID: 8665193

Claim:
A liquid crystal display (LCD) comprising: first and second electrodes formed to face each other; and a liquid crystal layer formed between the first electrode and the second electrode, and having a bent alignment, wherein a normal data voltage that indicates luminance corresponding to external image information and an impulse data voltage that indicates a lower luminance than a luminance of the normal data voltage with respect to at least one gray level are alternately applied to the first electrode, wherein the impulse data voltage includes a first impulse data voltage with a value that changes according to the external image information and a second impulse data voltage with a value that does not break the bent alignment, a number of applications of the first impulse voltage is two times or more a number of applications of the second impulse voltage, wherein the normal data voltage with respect to a certain gray level has a smaller voltage than a predetermined threshold voltage at which the bent alignment is broken.
