A liquid crystal display device comprises a first and second display panels that display a first image and a second image, respectively based on input image data of m bits, and are both driven by n bits, where n<m, a first gradation decision unit that decides an output gradation of n bits for the first display panel based on a first gradation characteristic, the output gradation of n bits for the first display panel and a second gradation decision unit that decides an output gradation of n bits based on a second gradation characteristic for the second display panel, the output gradation of n bits for the second display panel. At least one of the first and second gradation characteristics includes a gradation inverting portion, where the output gradation decreases when the input gradation rises.
