Abstract: There is provided a liquid crystal display device capable of suppressing coloring of an image when a liquid crystal panel is viewed in an oblique direction. An optical filter (4) is arranged on the front-most surface of the liquid crystal panel (11). The optical filter (4) changes transmittance when visible light of a predetermined wavelength range is emitted in an oblique direction than when emitted in the front direction. When a wide color range light source such as an LED is employed as a light source (8) of a backlight unit (12), the entire screen appears reddish and the color temperature tends to be lowered if the liquid crystal panel (11) is viewed in an oblique direction. In this case, by configuring the optical filter (4) so as to selectively attenuate the intensity of the red-based visible light range and increase the intensity of the blue-based visible light range, it is possible to suppress reddish-ness of the screen when viewed in an oblique direction.
