Patent number: 11700759Abstract: Disclosed is a display device capable of reducing the thickness and the weigh thereof. In an organic light-emitting diode display device having a touch sensor, a plurality of routing lines, which are connected respectively to a plurality of touch sensors disposed on an encapsulation unit, are disposed on different planes so as to overlap each other and are electrically connected to each other through a plurality of routing contact holes. Thereby, a connection fault between the routing lines is prevented. In addition, through the provision of the touch sensors above the encapsulation unit, a separate attachment process is unnecessary, which results in a simplified manufacturing process and reduced costs.Type: GrantFiled: January 14, 2022Date of Patent: July 11, 2023Assignee: LG DISPLAY CO., LTD.Inventors: Sang Hyuk Won, Min Joo Kim, Jae Won Lee, Sang Hoon Pak, Byong Hoo Kim, Sang Heun Lee, Hyang Myoung Gwon, Jeong Hoon Lee
