PURPOSE: A color LCD(Liquid Crystal Display) device is provided to achieve the compatibility or reduction in power consumption with high picture quality, particularly, improved color uniformity. CONSTITUTION: A color LCD device includes an LCD panel(100) and a backlight unit(103). The LCD panel includes color filters corresponding to primary red, primary green and primary blue. The backlight unit is disposed behind the LCD panel. The color LCD device satisfies a relationship that an isochromatic viewing angle is larger than a half-brightness angle, for at least one azimuthal viewing angle. The half-brightness angle is defined as an angle of a direction inclines with respect to a normal direction of the LCD panel in which brightness of light emerging from the backlight unit into the LCD panel becomes 50% of that in the normal direction. The isochromatic viewing angle is defined as a range of viewing angles from the normal direction. An absolute shift in an x coordinate of the primary red viewed at off-normal angles is not greater than 0.0314. An absolute shift in a y coordinate of the primary green viewed at off-normal angles is not greater than 0.0273. An absolute shift in a z coordinate of the primary blue viewed at off-normal angles is not greater than 0.0177.
