Liquid crystal display with high color gamut

A display comprising:

• a color filter having a plurality of green filter units having transmittance ranging from about 0.1% to about 60% at the optical wavelength of about 500 nm, and a plurality of blue filter units having transmittance ranging from about 0.1% to about 50% at the optical wavelength of about 500 nm;
• and
• a light tube having a first phosphor with a first peak emission wavelength between about 440 nm and about 460 nm, a second phosphor having a second peak emission wavelength between about 540 nm and about 550 nm, and a third phosphor having a third peak emission wavelength between about 500 nm and about 530 nm,
• wherein the intensity ratio of the second peak emission wavelength to the first peak emission wavelength ranges from about 0 to about 3.6, and the intensity ratio of the third peak emission wavelength to the first peak emission wavelength ranges from about 0.8 to about 2.7.
