Patent number: 11644726Abstract: A display device includes two adjacent pixel electrodes spaced apart from each other by a gap extending in a first direction, at least one signal line extending in the first direction and having at least one protrusion at at least one side thereof, and two adjacent common electrode lines spaced apart from each other. The orthogonal projection of one/the other common electrode line on the substrate is located between the orthogonal projection of the signal line on the substrate and the orthogonal projection of one/the other pixel electrode on the substrate. Each common electrode line has a bend segment bending away from the signal line, wherein the protrusion of the at least one signal line positionally corresponds to the bend segment of each common electrode line, and the length of the protrusion is not larger than the length of the bend segment.Type: GrantFiled: March 24, 2022Date of Patent: May 9, 2023Assignee: Au Optronics CorporationInventors: Hung-Che Lin, Yi-Chu Wang, Chien-Huang Liao, Yi-Tse Lin, Fu-ming Yu
