Abstract: A liquid crystal display device that includes an array substrate, an opposite substrate and a liquid crystal display layer is described. The array substrate includes a pixel electrode and a lower alignment layer. The pixel electrode has a plurality of slit portions extending in different directions. The lower alignment layer includes a reactive mesogen (RM) diamine is formed on the pixel electrode to induce an alignment direction of the liquid crystal molecules. An upper alignment layer is formed on a common electrode of the opposite substrate. The RM is cured at surfaces of the lower and upper alignment layers in response to ultraviolet (UV) light, so that liquid crystal molecules have a pretilt angle. Therefore, the aperture ratio and the response time may be improved, and afterimages may be decreased, so that display quality may be improved.

Abstract: A liquid crystal display includes a liquid crystal display panel having a first substrate and a second substrate. An upper polarizer is disposed on an outer surface of the first substrate. A viewing angle control film is disposed on the upper polarizer. The viewing angle control film includes a polarizing layer having a transmission axis substantially parallel to a transmission axis of the upper polarizer and a phase retardation layer including a birefringence material having an optical axis with a poloidal angle of about 40 degrees to about 75 degrees.

Abstract: A display panel includes a first substrate, a second substrate, a liquid crystal layer, a first polarizer, a second polarizer and a viewing angle control layer. The second substrate faces the first substrate. A liquid crystal layer is disposed between the first substrate and the second substrate. A first polarizer is disposed on a lower surface of the first substrate and includes a first polarizing layer and a second polarizing layer stacked on each other. A second polarizer is disposed on an upper surface of the second substrate. A viewing angle control layer is disposed on the first polarizer and is configured to control a viewing angle of a column direction of the display panel.
