    • PURPOSE: A reflective antiferroelectric LCD(liquid crystal display) is to use a polarizing plate and a phase delaying plate to provide a high iso-contrast ratio and luminance, a wide viewing angle and a fast responding characteristic. CONSTITUTION: A metal electrode(20) is formed on a strip of a first substrate(10). A transparent electrode(40) is formed on a strip of a second substrate(30) orthogonal to the metal electrode. An alignment film(50) is coated on the second substrate. Antiferroelectric liquid crystal is injected between the first and second substrates. A phase delaying plate(70) is formed on the second substrate on which the electrode is not formed. A polarizing plate(80) is formed on the phase delaying plate. Each molecule of the liquid crystal has an inclined angle between 20 to 60. A multiplying value of a thickness of the antiferroelectric liquid crystal and an optical anisotropy is between one eights of a wavelength and a half of the wavelength.
