A liquid crystal display device, comprising:
- a liquid crystal panel;
- a backlight that is arranged on a rear surface of the liquid crystal panel and that has LEDs as light sources, each of the LEDs comprising elements that respectively emit light of a red color, a green color, or a blue color;
- a signal generating section that generates an LED data signal on the basis of display image information, the LED data signal adjusting a light-emitting luminance of the LEDs;
- and
- a backlight driving section that controls the LEDs being turned ON and OFF on the basis of the LED data signal,
- wherein the backlight driving section comprises:
- an LED adjusting table including a plurality of correction coefficients that correct chromaticity of the LEDs;
- and
- an LED data signal correcting section that corrects the LED data signal with the control coefficients by referring to the LED adjusting table.
