The liquid crystal light modulator includes a first substrate (10) and a second substrate (20) disposed between two polarizers, and a pair of electrode structures (24, 24). The substrates include homeotropic alignment films (12) and (22), and at least one of the substrates has a function of aligning C-directors of liquid crystal molecules along one direction. The one direction forms an azimuth angle in the range of 35 to 55 degrees with the direction of the electric field generated by the pair of electrode structures (24, 24). A liquid crystal composition layer (31) contains a ferroelectric liquid crystal composition having a chiral smectic C phase or a liquid crystal composition that has an achiral smectic C phase and negative dielectric anisotropy. Light transmittance is modulated by the electric field generated by the electrode structures (24, 24) changing the birefringence index of the liquid crystal composition layer (31).

One or more devices, systems, methods and/or apparatus to facilitate suppression of fringe field effect, such as for diffraction grating and/or display purposes. In one embodiment, a ferroelectric liquid crystal (FLC) element can comprise a pair of conductive substrates, a FLC layer having a helical pitch and positioned between the conductive substrates, one or more spacers fixedly positioned between the conductive substrates, and an alignment layer positioned between the FLC layer and one of the conductive substrates. The alignment layer can be disposed at least partially contiguous with the FLC layer. The FLC layer can comprise a chiral smectic C* liquid crystal layer having at least one of a helical pitch smaller than an average cell gap of the FLC layer, or an average helical pitch of the FLC layer being smaller than an average thickness of the FLC layer between the conductive substrates.

The invention relates to the field of optoelectronics, and may be used in devices and of visualization, displaying, storage and processing of information, in particular in projection displays, etc. Video projector consists of a liquid crystal micro display based on structure FLCoS, and an optical unit of reading the information formed in the structure FLCoS, containing a light source and projection optics, optically coupled to the structure FLCoS, and a screen, onto which the information is projected. As the electro-optical material the low-voltage ferroelectric liquid crystal (FLC) with compensated helix providing physically realizable, continuous, halftone, hysteresis-free modulation characteristic is used in the structure FLCoS. Lasers of red, green and blue radiation serve as the sources of light in three different color channels RGB. To destroy the ability of their radiation to the interference, a cell with FLC is inserted into the optical unit of information reading that implements fast electrically controlled spatial phase light modulation with a depth of , and in order to form on the screen the information blocks with a capacity of 10.sup.8 . . . 10.sup.9 pixels, with different geometric configurations a two-dimensional scanner is input, which optically coupled to the optical unit of information reading and to the screen. The technical result is an increase of frame rate, expanding the color gamut, brightness enhancement, noise reduction.
