Patent ID: 8144141

Claim:
A liquid crystal display comprising: a light source unit including a light source having a plurality of divided lighting sections to be separately controlled and a light source control section controlling a light quantity of each of the divided lighting sections by a light control signal; a liquid crystal display panel including a plurality of pixels each having a liquid crystal element, a pixel electrode and a common electrode, and modulating light emitted from the light source based on an inputted video signal; and a display driving section performing a polarity inversion driving by applying driving voltages with waveform of alternately-inverting polarity based on the inputted video signal to the pixel electrode of each of the pixels, while maintaining the common electrode at a common potential, wherein the display driving section corrects the inputted video signal, separately for each of divided display regions in the liquid crystal display panel corresponding to ON-state divided lighting sections, based on the light control signal from the light source control section, so that a amplitude center potential of the driving voltage with a waveform of alternately-inverting polarity substantially agrees with the common potential, irrespective of the light quantity of the divided lighting section, and then the display driving section applies a driving voltage based on a corrected video signal to the liquid crystal element.
