摘要：
A method of evaluating a color filter including a substrate, and at least three color pixels disposed thereon, the method includes determining an oblique visibility of a liquid crystal display device equipped with the color filter on the basis of value ξ1 obtained from the equation (1): ξ1=∫abΔ(λ)·T(λ)dλ (1) wherein “a” and “b” are values respectively representing a wavelength range of a continuous wavelength light and satisfying conditions of 380≦a, b≦780 and a
