ABSTRACT:
A liquid crystal cell is constituted by a pair of substrates respectively provided with scanning electrodes or data electrodes and uniaxial alignment axes which are substantially parallel with each other and substantially in the same direction, and a ferroelectric liquid crystal disposed between the substrates. At least one of the substrates is provided with ridges having a height at least one third of the spacing between the substrates or stripe transparent electrodes having thereon a stripe conductor film extending in the longitudinal direction of an associated one of the stripe transparent electrodes.
