Abstract
A color filter includes red, green and blue filter segments and is adapted to be used in a liquid crystal display device using, as a light source, a white LED having specified spectral properties. The red filter segment has a 50% transmittance wavelength within a range of 595 to 610 nm and a transmittance of 85% or more at a wavelength of 630 nm. The blue filter segment has a maximum transmittance wavelength of 455 nm or less and a transmittance of 55% or more at a wavelength of 450 nm. A thickness of each of the red, green and blue filter segments is 3.0 μm or less. A liquid crystal display device including this color filter and the white LED is also disclosed.
