Both the liquid crystal material and the alignment layer material contain ionic compounds.

The alignment layer of an L.C.D. is designed to position the molecules so that they lie parallel to one another along the grooves.

Alignment layer causes perpendicular stacked alignment.

The Blue Phase mode can make its own alignment layers, eliminating the need for any mechanical alignment and rubbing processes.

When sandwiched between upper and lower alignment layers that have grooves pointing in different directions, L.C.D. molecules move naturally into a twisted spiral structure.

CLEAR's Services Oriented Alignment layer can be used to provide the specification for a Service-oriented architecture approach.

This operational mode for LCDs also does not require anisotropic alignment layers (e.g., rubbed polyimide) and thus theoretically simplifies the LCD manufacturing process.

The particular direction of the alignment of a nematic liquid crystal can be set by placing it in contact with an alignment layer or director, which is essentially a material with microscopic grooves in it, on the supporting substrates.
