Claim:
1. A liquid crystal display device comprising: a viewer-side polarizing plate; a liquid crystal cell; a backlight-side polarizing plate; and a backlight unit, wherein the backlight unit emits blue light which has a light emission central wavelength in a wavelength range of 430 nm to 470 nm and has a full width at half maximum of a light emission intensity of 50 nm or lower, green light which has a light emission central wavelength in a wavelength range of 510 nm to 560 nm and has full width at half maximum of a light emission intensity of 50 nm or lower, and red light which has a light emission central wavelength in a wavelength range of 610 nm to 660 nm and has a full width at half maximum of a light emission intensity of 50 nm or lower, and the viewer-side polarizing plate includes at least one of a first absorption material which has a maximum value of absorbance in a wavelength range of 470 nm to 510 nm and has a peak of the absorbance a full width at half maximum of which is 50 nm or lower, and a second absorption material which has a maximum value of absorbance in a wavelength range of 560 nm to 610 nm and has a peak of the absorbance a full width at half maximum of which is 50 nm or lower.
