The invention relates to a reactive mesogen (RM) formulation comprising a conductive additive, to a polymer film obtained thereof, and the use of the RM formulation and polymer film in optical or electrooptical components or devices, like optical retardation films for liquid crystal displays (LCDs).

Reactive mesogen formulation with conductive additive

A photolithiographic method for fabricating bank structures with improved non-wetting properties to form well regions on a substrate using a photoresist composition comprising a cresol novolak resin, a photoactive diazonaphthoquinone sulfonic ester of a polyhydroxybenzophenone compound with at least one free hydroxyl group, and a non-ionic urethane polyglycol fluorosurfactant. Inkjet methods can be used to deposit active materials into the well areas. Color filter arrays and optoelectronic devices such as OLED devices can be made by this method.

Patterned bank structures on substrates and formation method

A polymerizable LC material comprising at least one di- or multireactive mesogenic compound selected from the group of compounds of formula I, at least one monoreactive mesogenic compound selected from the group of compounds of formula II, wherein the parameter Ato A, L, p, Pto P, R, Spto Sp, Xto X, and Zto Zhave one of the meanings as given in claim, and at least one carbazole oxime ester photoinitiator. Furthermore, a method for preparation of the polymerizable LC material, a polymer film with improved thermal durability obtainable from the corresponding polymerizable LC material, a method of preparation of such polymer film, and the use of such polymer film and said polymerizable LC material for optical, electro-optical, decorative or security devices.

Polymerisable liquid crystal material and polymerised liquid crystal film

The invention relates to reactive mesogens (RMs) comprising a terphenyl group, to mixtures and formulations comprising them, to polymers obtained form such RMs and RM mixtures, and the use of the RMs, RM mixtures and polymers in optical or electrooptical components or devices, like optical retardation films for liquid crystal displays (LCDs).

Reactive mesogens

The invention relates to a method of preparing a polymer film and to the use of such polymer film as in liquid crystal displays (LCDs) or other optical or electro optical devices, for decorative or security applications, as alignment layer or optical retardation film.

Method of preparing a birefringent polymer film
