Patent number: 8482709Abstract: In a liquid crystal display, a first alignment layer formed on a first substrate includes a first region aligned in a first direction and a second region aligned in a second direction opposite to the first direction, and a second alignment layer formed on a second substrate facing the first substrate includes a third region aligned in a third direction different from the first direction and a fourth region aligned in a fourth direction opposite to the third direction. The liquid crystal molecules interposed between the first and second alignment layers are aligned in different directions in different domains defined by the first to fourth regions. A pixel electrode includes an extension part extending in at least one of the first to fourth directions. The aperture ratio and the light transmittance of the liquid crystal display are improved.Type: GrantFiled: April 13, 2011Date of Patent: July 9, 2013Assignee: Samsung Display Co., Ltd.Inventors: Kyoungju Shin, YongHwan Shin, Janwoo Lee, Young Gu Kim, Hyeongchan Ko, Hyunku Ahn, Baekkyun Jeon, Kyoungtae Kim, Gyo Jic Shin, Tai-Huem Om, Min-Sik Jung, Hoi-Lim Kim, Jin-Soo Jung
