ABSTRACT:
In a liquid crystal display device having an optical low-pass filter provided on a display screen, the optical low-pass filter is fixed to a liquid-crystal panel or a polarizing plate through a bonding layer having a refractive index different from the refractive index of the optical low-pass filter in a state where a surface having an optical function of the optical low-pass filter is directed toward a liquid-crystal panel or the polarizing plate. Further, in a liquid crystal display device having a phase plate, an optical low-pass filter is integrally formed on a phase plate. The occurrence of rainbow-shaped interference fringes is prevented. A liquid crystal display device is miniaturized and the number of components thereof is reduced. The fabrication precision of an optical low-pass filter is improved.
