Abstract:
A liquid crystal display for displaying an image to be visible for a viewer, comprising:a liquid crystal; a pair of electrodes for controlling an orientation of at least a part of the liquid crystal in accordance with an electric field between the electrodes; a light source for generating a light to be transmitted through the liquid crystal to the viewer; a pair of first and second polarizer plates, the first polarizer plate being arranged between the liquid crystal and the light source, and the second polarizer plate being arranged between the liquid crystal and the viewer; and a band-pass filter for absorbing a component of the light, a wave-length of which component is not more than 440 nm, and the band-pass filter being arranged between the light source and the viewer; wherein a permeability of the band-pass filter for the component of wave-length not more than 440 nm is smaller than a permeability of the band-pass filter for another component of the light, a wave-length of which another component is not less than 450 nm.
