Abstract: A liquid crystal display device includes an upper substrate and a lower substrate facing each other, alignment layers, and a liquid crystal layer. An alignment layer is disposed on the upper substrate and an alignment layer is disposed on the lower substrate. The alignment layer includes a vertical alignment layer and a tilting alignment layer. The vertical alignment layer includes a polyimide-based polymer resin having an imidization ratio of about 65% to about 90%. The tilting alignment layer is present on an upper portion of the vertical alignment layer and includes a pattern. The liquid crystal layer is interposed between the upper substrate and the lower substrate.

Abstract: An alignment layer, a liquid crystal display device, and a method for manufacturing the same. The alignment layer includes a first substance for forming a first main chain and a second substance for forming a second main chain on a substrate. The first substance is bonded to photocuring agents, and the second substance is bonded to vertical alignment groups. The photocuring agents are crosslinked to each other and are aligned at a pretilt angle with respect to the substrate. The vertical alignment groups are aligned substantially vertically to the substrate. The first and second substances are different from each other.
