A chromaticity correction device corrects chromaticity of a video signal displayed on a display panel of a display device to correspond to a change in a luminance value of the display panel. The chromaticity correction device includes a luminance detection unit which detects the luminance value, a backlight driving level detection unit which detects a backlight driving level, a temperature detection unit which detects an internal device temperature or an ambient temperature, a reference luminance value calculation unit which estimates a reference luminance value in a characteristic of an initial state, a chromaticity calculation unit which obtains a chromaticity change amount of white point chromaticity and estimated white point chromaticity that is an estimated value of current white point chromaticity, a chromaticity correction value calculation unit which obtains a chromaticity correction value and a chromaticity correction circuit which corrects the chromaticity of the video signal.
