摘要： A liquid crystal display includes: a light source section including a plurality of lighting sections; a light source driving section for determining a light intensity of each lighting section according to the image signal inputted and driving the light source section so that each lighting section is independently activated with the light intensity determined; a liquid crystal display panel; and a display driving section for driving the liquid crystal display panel based on the image signal. In a case that a display region corresponding to the lighting section includes a high-luminance part and a low-luminance part, the display driving section corrects the image signal in the low-luminance part so that the display luminance of the low-luminance part results in the same level as the display luminance under a maximum light intensity of the corresponding lighting section, and drives the low-luminance part according to the image signal corrected.
