    Abstract: A liquid crystal display device comprises: a first display panel displaying a color image; a second display panel displaying a monochrome image; and an image processor generating first image data corresponding to the color image and second image data corresponding to the monochrome image based on an input video signal. The image processor generates the first image data and the second image data such that a graph representing transmittance of the first display panel for input gradation corresponding to the input video signal and a graph representing transmittance of the second display panel for the input gradation corresponding to the input video signal intersect each other at predetermined input gradation.

    Abstract: A liquid crystal display device includes: a first display panel displaying a color image; a second display panel that is disposed farther away from the observer with respect to the first display panel and displays a monochrome image; and an image processor that generates color image data and monochrome image data. The image processor includes an extension filtering unit that performs extension filtering on first monochrome image data, which is made monochrome using a maximum value in a value of each color expressing color information included in the input video signal. The extension filtering unit performs the extension filtering on the first monochrome image data using a large filter size in a larger luminance difference region, and performs the extension filtering on the first monochrome image data using a small filter size in a small luminance difference region.
