LIQUID CRYSTAL DISPLAY DEVICE, METHOD OF MANUFACTURING THE SAME AND ALIGNMENT LAYER COMPOSITION FOR THE LIQUID CRYSTAL DISPLAY DEVICE

摘要

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.

1. A method of manufacturing an LCD device, the method comprising:
forming a lower alignment layer on an array substrate comprising a pixel electrode having a plurality of slit portions inducing an alignment direction of liquid crystal molecules, the lower alignment layer including an RM; coupling an opposite substrate to the array substrate; providing a liquid crystal layer between the lower alignment layer and the array substrate; and irradiating the lower alignment layer with light under conditions in which an electric field is applied to the liquid crystal layer through the pixel electrode to provide a pretilt angle to liquid crystal molecules at a surface of the lower alignment layer.
