摘要： An LCD device is discussed, which comprises first and second substrates confronting each other; a liquid crystal layer between the first and second substrates; and red, green, blue, and fourth color filters on the first substrate; wherein the fourth color filter is formed of any color whose transparency is better than that of at least one of the red, green, and blue color filters, and wherein an effective area of the fourth color filter is smaller than that of at least one of the red, green, and blue color filters. The LCD device can display white color with good transparency by properly adjusting the effective areas of the four color filters, whereby there is no need to modulate light for display of the white color in a backlight unit, to thereby improve luminance of light emitted from the backlight unit.
