Publication number: 20220115630Abstract: A method for manufacturing a display device is provided. A process of forming an inspection pattern, in which a protective film unit is partially removed in a thickness direction, in a pad area portion of the protective film unit, which corresponds to a pad area of a display unit, may be performed, and then, a process of delaminating the pad area portion of the protective film unit may be performed. A process of checking whether the inspection pattern exists may be performed to check whether the delamination has succeeded, and, at the same time, a process of measuring distances from an alignment mark to each of a long side and a short side of the display unit may be performed.Type: ApplicationFiled: December 17, 2021Publication date: April 14, 2022Inventors: Beomjun Cheon, Kyungsik Kim, Yun-seok Eo, Sang-geun Lee, Seungkuk Lee, Sehee Lim, Jinsoo Choi

Patent number: 11067856Abstract: A display apparatus comprises a first substrate comprising a first external surface and a first internal surface; a second substrate having a second external surface and a second internal surface facing the first internal surface of the first substrate; and a display unit disposed between the first and second substrates and comprising an array of pixels. The first substrate comprises a first side connecting the first external surface and the first internal surface. In a cross section perpendicular to the first external surface, the first side comprises a first straight region and a first curved region located between the straight region and the first internal surface. The second substrate comprises a second side connecting the first external surface and the first internal surface. The second side comprises a second straight region and a second curved region located between the straight region and the second internal surface.Type: GrantFiled: May 1, 2020Date of Patent: July 20, 2021Assignee: Samsung Display Co., Ltd.Inventors: Hyoengki Kim, Sangwook Sin, Jaeyoung Shin, Seungjoon Yoo, Jaeman Lee, Hyunsoo Lee, Beomjun Cheon, Gwangjoon Hong
