  • Fringe field switching LCD having smectic liquid crystal and utilizing alternate current squared wave driving voltage
    Patent number: 7633588
    Abstract: 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.
