A color filter is provided with a red filter segment, a green filter segment and a blue filter segment on a substrate. The color filter is suitable for a liquid crystal display device wherein a white LED is used as a light source. The white LED has spectroscopic characteristics wherein a wavelength (λ1) has maximum emission intensity within a range of 430nm-485nm, a peak wavelength (λ2) of a second emission intensity within a range of 530nm-580nm, and a ratio (I2/I1) of an emission intensity (I2) with the wavelength (λ2) to an emission intensity (I1) with the wavelength (λ1) is 0.2 or more but not more than 0.7. The red filter segment has a 50% transmittance wavelength within a range of 595-610nm, and a transmittance of 85% or more with a wavelength of 630nm. The blue filter segment has a maximum transmittance wavelength of 455nm or less, and a transmittance of 55% or more with a wavelength of 450nm. Each thickness of the red filter segment, the green filter segment and the blue filter segment is 3.0μm or less. The liquid crystal display device provided with the color filter and the white LED as the light source is also disclosed. |
