发明名称 Liquid crystal display device having red, green and blue filters in which the liquid crystal layer thickness for the red filter portion is equal to the green filter portion but greater than the blue filter portion
摘要 First and second polarization plates are disposed on both sides of a liquid crystal panel in which thicknesses of a liquid crystal layer are set up depending on colors of color filters. Then, a first retardation film is disposed between the liquid crystal panel and the first polarization film, and a second retardation film is disposed between the liquid crystal panel and the second polarization film. Assuming that a maximum value of a refractive index in an in-plane direction out of principal indices of refraction is Nx, that a refractive index in an orthogonal direction to the direction of the refractive index which has the value of Nx is Ny, and that a thickness is d, the first and second retardation films are set to satisfy a difference in values of (Nx-Ny)xd equal to or less than 10 nm.
