METHOD FOR PRODUCING A LAYER WHICH INFLUENCES THE ORIENTATION OF LIQUID CRYSTAL AND A LIQUID CRYSTAL CELL WHICH HAS AT LEAST ONE LAYER OF THIS TYPE

摘要

To reduce the disadvantages of conventional liquid-crystal orientation layers, or of liquid crystal cells having such layers, it is proposed to deposit the orientation layer on a substrate from a plasma of a gas discharge, the gas having at least one hydrocarbon, particularly a monomeric hydrocarbon. The method of the present invention allows the angle of tilt of the liquid crystals adjacent to the orientation layer to be defined and reproducibly adjusted, thus improving the contrast and the rise time of light modulators.
