A liquid crystal display panel including several first electrode portions, several second electrode portions, and a smectic liquid crystal layer is provided. The first electrode portions and the second electrode portions are disposed on a first substrate. When an AC voltage is applied on the first electrode portions and the second electrode portions, the direction of a horizontal electrical field formed between each first electrode portion and the adjacent second electrode portion is parallel to the surface of the first substrate. The smectic liquid crystal layer is interposed between the first substrate and a second substrate. During the phase change of a liquid crystal molecule of the smectic liquid crystal layer, the horizontal electrical field generated by applying the AC voltage on the first electrode portions and the second electrode portions facilitates the alignment of the liquid crystal molecule of the smectic liquid crystal layer.

An LCD panel including a first substrate, a second substrate and a smectic liquid crystal layer is disclosed. The first substrate includes a first electrode, a second electrode and a first horizontal alignment film. The first electrode has plural first portions. The second electrode has plural second portions. The first portions are spaced by the second portions. The electrical field directions formed between the first portions and the second portions are perpendicular to the surface of the first substrate. The electrical field direction on each first portion is opposite to that on each second portion. The first horizontal alignment film covers the first and the second electrodes. The second substrate includes a second horizontal alignment film. The horizontal rubbing direction of the first horizontal alignment film is parallel to that of the second horizontal alignment film. The smectic liquid crystal layer is sealed between the first and the second substrates.

The present invention relates a chiral compound, comprising a general formula as formula (I):

Ferroelectric liquid crystal material derived from lactic acid

A chiral swallow-tailed liquid crystal is provided. The present chiral swallow-tailed liquid crystal is synthesized from a chiral material. The present chiral swallow-tailed liquid crystal is composed of the compound of (N,N&prime;-diethyl (s)-2-&lcub;6-&lsqb;4-(4&prime;-alkoxyphenyl)benzoyloxy&rsqb;-2-naphthyl&rcub;propanamide or the compound of (N,N&prime;-dipropyl(s)-2-&lcub;6-&lsqb;4-(4&prime;-alkoxyphenyl)benzoyloxy&rsqb;-2-naphthyl&rcub;propanamide. The chiral center of the present chiral compound is directly linked to its rigid core, and the chiral tail of this compound is linked with a swallow-tailed group. The chiral center and swallow-tailed group are arranged at the same side in the molecular structure. This structural characteristic enables the chiral compound to have the same property of thresholdless antiferroelectricity, and the advantage of simple manufacturing process. The present chiral compound shows an optimum application effect in liquid crystal displays.
