Abstract

A liquid crystal display device includes: a first display panel displaying a first image; a second display panel displaying a second image; and an image processor generating first and second image data based on input video signal. The image processor includes a first differential filtering processor, a multiplier that multiplies a grayscale of the image data subjected to the differential filtering by the first differential filtering processor by a correction coefficient, and a first smoothing processor that performs smoothing processing on image data obtained by adding the image data multiplied by the correction coefficient and the image data based on the input video signal. The image processor generates the first image data based on the image data based on the input video signal and the image data subjected to the smoothing processing, and generates the second image data based on the image data subjected to the smoothing processing.
