Liquid crystal display

Abstract

A spectrum of light which is emitted from an illuminator () of a liquid crystal display device () has a peak in each of the wavelength ranges of 447 to 453 nm, 538 to 542 nm, 613 to 617 nm, 628 to 632 nm, and 648 to 652 nm. The peak wavelength and rising wavelength of the transmission spectrum of the red color filters are, respectively, not less than 600 nm; and not less than 568 nm and not more than 572 nm. At wavelengths of 400 nm, 420 nm and 580 nm, the transmission spectrum of the red color filters has transmittances of, respectively, 10 to 15%; 3 to 6%; and 25 to 30%. The wavelengths at which the transmission spectrum of the red color filters exhibits a transmittance of 50% are contained within a range of 583 to 587 nm. The peak wavelength of the transmission spectrum of the green color filters is not less than 500 nm and not more than 560 nm. At wavelengths of 480 nm and 580 nm, the transmission spectrum of the green color filters exhibits transmittances of, respectively, 45 to 55%; and 65 to 70%. The wavelengths at which the transmission spectrum of the green color filters exhibits a transmittance of 50% are contained within a range of 478 to 482 nm and a range of 590 to 600 nm. The peak wavelength of the transmission spectrum of the blue color filters is not less than 440 nm and not more than 470 nm. At wavelengths of 400 nm and 500 nm, the transmission spectrum of the blue color filters exhibits transmittances of, respectively, 25 to 40%; and 40 to 50%. The wavelengths at which the transmission spectrum of the blue color filters exhibits a transmittance of 50% are contained within a range of 493 to 503 nm.
