Abstract: A liquid crystal display may include a substrate and a color filter set disposed on the substrate. The color filter may include a blue color filter. The blue color filter may include a blue pigment, a violet dye, and a violet absorbing pigment. The violet absorbing pigment may absorb light having a wavelength in a range of 410 nm to 450 nm. The blue color filter may have transmittance in a range of 20% to 30% with respect to light having a wavelength in a range of 425 nm to 435 nm.
