A liquid crystal display (LCD) having color filters configured according to optical characteristics of a field emission backlight. The LCD includes: a display panel having color filters including red, green, and blue filters; and a backlight device at a rear side of the display panel and including a vacuum panel with a cold cathode electron source and a phosphor layer that is excited by electrons emitted from the cold cathode electron source to emit visible light. Here, a wavelength position corresponding to a half of a peak intensity of a transmission spectrum of the red filter is at from about 570 nm to about 622 nm, a wavelength position corresponding to a half of a peak intensity of a transmission spectrum of the blue filter is not greater than 520 nm, and/or a transmission spectrum of the green filter has a full width at half maximum (FWHM) ranging from about 60 nm to about 115 nm.
