Patent number: 8958035Abstract: A wide variety of different alignment polar angles can be created in the alignment layers of a liquid crystal display with just a small number of UV exposure steps by using one or a combination of overlappable UV masks, where the one or more combinations of overlappable UV masks simultaneously define a maximal transmission region, an intermediate transmission region and a nontransmitting (blocking) region. UV rays are irradiated through masks in different irradiation directions while the mask or masks are disposed in different orientations.Type: GrantFiled: September 2, 2010Date of Patent: February 17, 2015Assignee: Samsung Display Co., Ltd.Inventors: Jun-Woo Lee, Jin-Soo Jung, Suk-Hoon Kang, Tae-Ho Kim, Soo-Ryun Cho, Baek-Kyun Jeon
