| abstract |
The present invention relates to a negative or positive (negative) material comprising a self-aligning additive (SAM) having at least one bifunctional or multifunctional anchor group, which makes a homeotropic (vertical) alignment of the liquid crystal medium at the surface or cell wall of the liquid crystal display To a liquid crystal medium having dielectric anisotropy. Thus, the present invention also includes a liquid crystal display having a homeotropic alignment of the liquid crystal medium without a conventional imide alignment layer. The liquid crystal medium can be supplemented by a polymerizable or polymerized component that functions as a stabilization of the alignment, adjustment of the tilt angle, and / or passivation layer. |
