Abstract:
A liquid crystal display includes a first substrate and a second substrate facing each other; a pixel electrode disposed on the first substrate; a first alignment layer formed on at least one of the first substrate and the second substrate; a second alignment layer disposed on a same substrate as the first alignment layer, and a liquid crystal layer interposed between the first substrate and the second substrate, where the first alignment layer is a rubbing alignment layer, and the second alignment layer is a photo-alignment layer. A method of manufacturing the liquid crystal display is also provided.
Abstract:
A photoalignment agent includes a polyimide and a capping terminal connected to a main chain end terminal of the polyimide. The capping terminal includes an alkylene group (—CmH2m—, m is a natural number) and a core stereo unit in a dendrimer format. A liquid crystal display includes a first substrate, a thin film transistor disposed on the first substrate, a first electrode connected to the thin film transistor, and a first alignment layer disposed on the first electrode. The first alignment layer includes a polyimide and a capping terminal connected to a main chain end terminal of the polyimide. The capping terminal includes an alkylene group (—CmH2m-, m is a natural number) and a core stereo unit in a dendrimer format.
Abstract:
A liquid crystal display includes a first substrate, a thin film transistor positioned on the first substrate, a first electrode connected to the thin film transistor, a second substrate facing the first substrate, a first alignment layer positioned on the first electrode and a second alignment layer positioned on the second substrate, and a liquid crystal layer positioned between the first substrate and the second substrate and including a liquid crystal molecule. At least one of the first alignment layer and the second alignment layer includes a copolymer of cyclobutanedianhydride (CBDA), a diamine, and a compound represented by Chemical Formula 2. In which X of Chemical Formula 2 represents —(CH2)m-O—(CH2)n—, and a sum of m and n is an odd number.

Abstract:
Provided is a liquid crystal display, including: a first substrate; a first electrode and a second electrode disposed on the first substrate and overlapping with each other with a first insulating layer therebetween; a second insulating layer disposed on the first substrate and having an opening; a second substrate facing the first substrate; a first alignment layer disposed on the first substrate; a second alignment layer disposed on the second substrate; and a spacer disposed between the first alignment layer and the second alignment layer, in which the spacer is positioned in the opening.
Abstract:
In a liquid crystal display, a pretilt value provided by an upper alignment layer or a lower alignment layer is gradually changed in one domain, such that liquid crystal molecules have various arrangements in which azimuth angles of aligned liquid crystal molecules are gradually changed.
