A filament or fiber () comprising a volume modulation coloration producing substance (); containment means () for containing the substance in the form of an elongated core which containment means is at least partially light transmitting; and stimulation means () for stimulating the substance to produce a change in the volume of the substance, thereby changing the color of the filament or fiber.

Fibre or filament

A fabric () formed from a plurality of first fibers or filaments (), and a plurality of second fibers or filaments (); the first fibers or filaments being non-conductive and comprising an electro-optically active material; and the second fibers or filaments being conductive; whereby a voltage difference between two second fibers causes a colour change in a first fiber positioned therebetween.

Fabric

The invention pertains to an alignment layer capable of aligning liquid crystal material, the alignment layer comprising: a first sublayer having regions capable of aligning the liquid crystal material in a first alignment, a second sublayer having regions capable of aligning the liquid crystal material in a second alignment, the first and the second alignment being different, the second sublayer overlaying the first sublayer and covering in accordance with a pre-determined pattern the first sublayer to provide, at desired locations, second sublayer regions capable of aligning the liquid crystal material and, at desired locations, regions of the underlying first sublayer that are not covered by the second sublayer, and to a method of making this alignment layer. The invention further relates to an optical or electro-optical device comprising said alignment layer.
