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.
