Publication number: 20230189578Abstract: An electroluminescent display device can include a substrate including an active area and a non-active area having a gate in panel (GIP) area, a thin film transistor disposed on the substrate, a GIP circuit unit disposed on the substrate in the GIP area, a sacrificial layer disposed on the GIP circuit unit, a planarization layer disposed over the thin film transistor and the sacrificial layer, an anode disposed on the planarization layer, a bank disposed on the planarization layer and exposing a portion of the anode, a light emitting unit and a cathode disposed on the anode and the bank, a trench pattern disposed on the sacrificial layer, and a buffer layer disposed on the cathode and an inner surface of the trench pattern. As a result, reliability of the display panel can be improved by preventing diffusion of residual foreign materials and moisture permeation.Type: ApplicationFiled: September 29, 2022Publication date: June 15, 2023Applicant: LG Display Co., Ltd.Inventors: Eonho CHA, GyuHyeong HAN, Yoonseok LEE, Hyemin HWANG, Jonghoon YEO

Patent number: 11641756Abstract: A display device and a method for manufacturing the same are disclosed, in which a cathode electrode is not separated from an organic light emitting layer. The method includes forming pixels on a display area on a first substrate, forming an encapsulation film to cover the display area, attaching a protective film onto the encapsulation film, and removing the protective film. The protective film includes a substrate layer and an adhesive layer formed at an edge area of at least one side of the substrate layer.Type: GrantFiled: May 26, 2021Date of Patent: May 2, 2023Assignee: LG DISPLAY CO., LTD.Inventors: GyuHyeong Han, Heechul Lim, ByoungChul Kim, Heesung Park
