A liquid crystal display panel includes a first substrate, a second substrate, a first alignment layer, a second alignment layer and a liquid crystal layer. The second substrate faces the first substrate. The liquid crystal layer is disposed between the first alignment layer and the second alignment layer. The first alignment layer and the second alignment layer each include a polyimide compound polymerized by cyclobutane-1,2,3,4-tetracarboxylic dianhydride and cyclobutane-1,2,3,4-tetracarboxylic dianhydride derivative.

Liquid crystal display panel and method of manufacturing the same

A liquid crystal display includes; a first substrate, a second substrate disposed facing the first substrate, an alignment layer disposed on at least one of the first substrate and the second substrate, wherein the alignment layer comprises a major alignment material and a vertical photo-alignment material, and the vertical photo-alignment material comprises a first vertical functional group, and a liquid crystal layer interposed between the first substrate and the second substrate.

Liquid crystal display and manufacturing method thereof

A liquid crystal display including: a first substrate and a second substrate facing each other; an alignment layer disposed on one of the first substrate and the second substrate and including a vertical photo-alignment material which includes a first vertical functional group and a photo-reactive group, and a major alignment material which does not include the photo-reactive group; and a liquid crystal layer disposed between the first substrate and the second substrate, wherein a ratio of a molar concentration of the vertical photo-alignment material to the molar concentration of the major alignment material increases in a direction towards a surface of the alignment layer adjacent to the liquid crystal layer.

A wide variety of different alignment polar angles can be created in the alignment layers of a liquid crystal display with just a small number of UV exposure steps by using one or a combination of overlappable UV masks, where the one or more combinations of overlappable UV masks simultaneously define a maximal transmission region, an intermediate transmission region and a nontransmitting (blocking) region. UV rays are irradiated through masks in different irradiation directions while the mask or masks are disposed in different orientations.

Mask for photoaligning an alignement layer, photoalignment method using the same, and liquid crystal display having the photoaligned alignement layer

A photoalignment method includes irradiating light in a first direction to a first alignment layer, and irradiating light in a second direction opposite the first direction, after disposing a first mask on the first alignment layer.
