Patent number: 10985301Abstract: A light-emitting device includes a supportive substrate and a first light-emitting element on the supportive substrate. The first light-emitting element includes a first light-emitting stacked layer having a first surface and a second surface opposite to the first surface, and a first transparent layer on the first surface and electrically connected to the first light-emitting stacked layer. A second light-emitting element locates on the supportive substrate and a metal layer electrically connects to the first light-emitting element and the second light-emitting element and physically connects to the first transparent layer. The first light-emitting stacked layer includes a first width and the first transparent layer includes a second width different from the first width from a cross section view of the light-emitting device.Type: GrantFiled: June 6, 2018Date of Patent: April 20, 2021Assignee: EPISTAR CORPORATIONInventors: Shih-I Chen, Chia-Liang Hsu, Tzu-Chieh Hsu, Han-Min Wu, Ye-Ming Hsu, Chien-Fu Huang, Chao-Hsing Chen, Chiu-Lin Yao, Hsin-Mao Liu, Chien-Kai Chung
