Patent number: 8081279Abstract: Disclosed is a liquid crystal display device including a first substrate where pixel areas are defined, a second substrate facing the first substrate, liquid crystals aligned between the first and second substrates, and spacers that maintain a gap between the first and second substrates. The pixel areas are divided into a plurality of domains along the alignment direction of the liquid crystals by way of domain dividers. Optical characteristics are compensated in different domains, so that the viewing angle of the liquid crystal display device is increased. The display quality of the liquid crystal display device is improved by adjusting the shape and position of the domain dividers and the spacers.Type: GrantFiled: May 25, 2007Date of Patent: December 20, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Sun-Kyu Joo, Myung-Sub Lee, Yun-Seok Lee
