Patent number: 10879218Abstract: A method of manufacturing a display device includes the following steps. A bonding pad is formed on a dielectric layer. A light-shielding material is formed on the dielectric layer. A temperature of the light-shielding material is increased such that the light-shielding material is cured into a light-shielding layer. During curing the light-shielding material into the light-shielding layer, the light-shielding material flows to and contacts a portion of a surface of the bonding pad. A light-emitting element is electrically connected to the bonding pad.Type: GrantFiled: December 2, 2019Date of Patent: December 29, 2020Assignee: AU OPTRONICS CORPORATIONInventors: Cheng-He Ruan, Jian-Jhou Tseng, Chih-Yuan Hou
