ABSTRACT:
A liquid crystal display (LCD) module includes a backlight module and an LCD panel. The backlight module has an illumination device for emitting at least a first, a second, and a third color light. The wavelength of the second color light is between 520 nm and 540 nm. The LCD panel is provided to display an image with the first, second and third color lights provided as light sources. The LCD panel includes a color filter having at least a first, a second, and a third filtering layer for filtering the first, second, and third color lights, respectively. The LCD panel also includes a liquid crystal layer disposed next to the color filter. The peak value of a transmission spectrum of the second filtering layer is between 520 nm and 540 nm, and the full width at half maximum of the transmission spectrum of the second filtering layer is between 90 nm and 120 nm.
