The present invention relates to a liquid-crystal material (LC media) comprising thiophene derivatives which are stabilised by sterically hindered amines or amine derivatives (HALS, hindered amine light stabilisers), and to liquid-crystal displays (LC displays) which contain these LC materials.

The present invention relates to liquid-crystal (LC) media as defined in claim 1, having negative dielectric anisotropy and to the use thereof for optical, electro-optical and electronic purposes, in particular in LC displays.

Liquid-crystalline media containing one or more mesogenic compounds, one or more chiral compounds, and one or more polymerizable mesogenic compounds, wherein the media exhibit a pitch of 0.55 μm or more and a clearing point of 80° C. or more and wherein the one or more polymerizable mesogenic compounds are contained in an amount, based on the overall contents of the media, of 5% by weight or less, are suitable as modulation materials. Such modulation materials can be used in switching layers and window elements.

There is provided the use of an aligned nematic elastomer to form a material having auxetic properties wherein the aligned nematic material has a mechanical Fréedericksz transition. Also provided is a method of producing an aligned nematic elastomer for said use.

The present disclosure provides a liquid crystal material, a method of manufacturing a liquid crystal display panel, and a display panel. The display panel includes a thin film transistor substrate, a color film substrate, a polymer layer structure, and a liquid crystal layer. During the preparation, after three different irradiations, the liquid crystal material is directly polymerized into the first polymer layer structure and the second polymer layer structure under the irradiations, eliminating the black matrix structure and the polyimide alignment film structure, improving the display effect of the panel, and reducing preparation costs.

A device includes a polymer stabilized blue phase liquid crystal (“PS-BPLC”) layer. The device also includes an alignment structure coupled with the PS-BPLC layer. LC molecules disposed in contact with the alignment structure are configured to have a spatially varying in-plane orientation pattern that is at least partially defined by the alignment structure. The PS-BPLC layer is configured to forwardly deflect a polarized light having a predetermined handedness, and transmit a polarized light having a handedness that is orthogonal to the predetermined handedness.

An object of the present invention is to provide a binder composition in which air unevenness is suppressed and which has excellent upper layer coating properties after being formed as a layer, a compound, a binder layer, an optical laminate, an optical laminate manufacturing method, and an image display device. The binder composition of the present invention is a binder composition containing a binder and a compound having a group represented by Formula (B1) or (B2).

Suggested are new adhesion promoters, which are particular suitable for use in displays. Its inclusion in the polymerisable LC mixture results in an excellent adhesion on substrate without colouration over time i.e. compared to amino siloxanes. The new additives have no effect on alignment of LC on the substrate while improving the adhesion.

An ionic liquid crystal elastomer composition includes a liquid crystal elastomer; and an ionic liquid.
