Abstract: A liquid crystal (LC) display device includes a first display panel, a second display panel, and an image processor. The image processor generates first image data and second image data that correspond to a first image and a second image for display on the first display panel and the second display panel, respectively. The image processor includes a first image data decision unit that decides the first image data, a filter that decides a correction factor, and a second image data decision unit that decides the second image data based on smoothed image data and the correction factor. A method for displaying an image in a LC display device with a first display panel and a second display panel includes determining first image data based on smoothed input image data, and determining second image data based on the smoothed input image data and a correction factor.
