Patent number: 10074504Abstract: 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.Type: GrantFiled: January 13, 2015Date of Patent: September 11, 2018Assignee: Samsung Display Co., Ltd.Inventors: Keun-Chan Oh, Jae-Jin Lyu, Ji-Won Sohn, Seon-Ah Cho
