Ferroelectric liquid crystal cell |
| abstract |
A liquid crystal display cell comprising a chiral ferroelectric smectic liquid crystal layer whose helix structure is influenced by the action of an electric field such that its optical anisotropy alters; a pair of transparent plates between which the liquid crystal is disposed and which have a surface structure for aligning the molecule of the liquid crystal and are provided with electrodes to produce an electric field therein; and one polariser each before and after the liquid crystal: such ratio d/p of the thickness d of the liquid crystal layer to the pitch height p of the helical twisting is greater than 5, the smectic tilt angle theta o is being between 22.5 DEG and 50 DEG and the product d. theta o2. DELTA n.1/ lambda (phase factor) of the thickness d, the square of the tilt angle theta o, the value of the birefringence DELTA n and the reciprocal of the wavelength lambda of light bedding is greater than 0.45 mu m. |
