Abstract
A liquid crystal display including a backlight unit and a liquid crystal display panel is provided. The backlight unit includes an exciting light source and quantum dot remote phosphor. Spectrum of the backlight unit has relative maximum brightness peaks BL1, BL2 and BL3 between 445 nm to 455 nm, between 528 nm to 538 nm, and between 618 nm to 628 nm, respectively. The liquid crystal display panel is disposed above the backlight unit and has a red color filter, a green color filter, a blue color filter and a yellow color filter, wherein areas of the red color filter, the green color filter, the blue color filter and the yellow color filter are ARAGABAY, respectively. The areas ARAGABAY satisfy the following relationship: 0.75<AR/AG<0.85; 0.3<AR/AB<0.4; and 0.95<AR/AY<1.05.
