Patent number: 8890861Abstract: In an electrophoretic display apparatus, a first substrate includes a plurality of pixels each including at least two sub-pixels which display colors different from each other, and a second substrate which faces the first substrate and includes a reference electrode corresponding to a boundary between adjacent sub-pixels in each pixel. An electrophoretic material is between the first substrate and the second substrate. A barrier wall is between the first substrate and the second substrate, and defines the pixels.Type: GrantFiled: September 8, 2011Date of Patent: November 18, 2014Assignee: Samsung Display Co., Ltd.Inventors: SonUk Lee, Seonggyu Kwon, Namseok Roh, Tae Hyung Hwang, Joo-Han Bae, Sang-Hee Jang

Patent number: 8879031Abstract: Exemplary embodiments of the present invention disclose a liquid crystal display (LCD) and a method of manufacturing the same. The LCD may have a display area and a peripheral area. An organic layer of the peripheral area may be patterned using a half-tone mask, and a protrusion member may be formed in the peripheral area. Accordingly, the thin film transistor array panel and the corresponding substrate may be prevented from being temporary adhered in the peripheral area such that the density of the liquid crystal molecules filled in the peripheral area may be uniformly maintained and the display quality of the liquid crystal display may be improved.Type: GrantFiled: October 4, 2013Date of Patent: November 4, 2014Assignee: Samsung Display Co., Ltd.Inventors: Kyung-Sook Jeon, Jang-Soo Kim, Hong-Suk Yoo, Yong-Hwan Kim, Hwa-Yeul Oh, Jong-In Kim, Sang-Hee Jang
