    • PURPOSE:To provide an antiferroelectric liquid crystal display element having a high contrast ratio for displaying light and shade and not affected by the change of the threshold value voltage due to temperature. CONSTITUTION:The long axis direction of the liquid crystal molecule of an antiferroelectric liquid crystal cell arranged between a pair of polarizing plates arranged on a cross nicol is inclined at an nonzero angle against the polarization direction of the polarizing plate on the incidence side in the antiferroelectric state while no voltage is applied. When a triangular wave is applied, the permeability is largely changed in the range of the fixed inclination angle, the permeability becomes O in the uniform ferroelectric state when the negative electrode side voltage is applied, high permeability is obtained in the uniform ferroelectric state when the positive electrode side voltage is applied, and a high contrast ratio 200 or above is obtained. A liquid crystal display element is driven by the voltage sufficiently higher than the threshold value voltage, and it is not affected by the change of the threshold value voltage due to temperature.

    • PURPOSE:To prevent visuality from being deteriorated by working burrs so that their height from a film face is uniformed and sticking the reflecting face side peripheral edge part of a reflecting member fast to the peripheral edge part of a cell on the optical film sticking side while holding a gap between the reflecting face and a film face. CONSTITUTION:An optical film 2 is stuck to one outer surface of a liquid crystal cell 1 and the peripheral edge part of the film 2 is cut off from the normal direction of a film surface by a mechanical means to form burrs 3 projecting from the film surface on the cut part. Then, the burrs 3 are worked so that the height from the film surface is uniformed and the reflecting face side peripheral edge part of the reflecting member is stuck fast to the optical film sticking peripheral edge parts on both the sides of the cell 1 while holding the gap between the reflecting face and the film face by the burrs 3. Consequently, the generation of a troublesome phenomenon such as interference stripes and double display can be prevented and the invasion of uncured sealing agent into the gap between the optical film and the reflecting plate immediately after its application can be suppressed.
