Patent ID: 7710517

Claim:
A liquid crystal display, comprising: a backlight; a polarization plate; at least two substrates; a liquid crystal layer placed between the substrates; and a color filter layer formed on at least a part of the substrates; wherein the color filter layer has green pixels that satisfy the relations 0.25<x<0.32 and y>0.58, wherein x and y each represent a chromaticity value in an xy color system using illuminant C, the color filter layer has a contrast of 1000 or more with respect to each of X, Y and Z values, the backlight uses a light-emitting device having a peak wavelength in the range of from 520 nm to 540 nm as a light source; and wherein the backlight comprises a green light-emitting diode (LED) having a peak wavelength in the range of from 520 nm to 540 nm, a blue LED having a peak wavelength in the range of 480 nm or less, and a red LED having a peak wavelength in the range of 610 nm or more, as light sources.
