Publication number: 20220246815Abstract: A light emitting element includes a semiconductor layered body, an insulating film, first and second electrodes, and first and second external connection portions. The semiconductor layered body defines exposed portions in which the first semiconductor layer is exposed from the second semiconductor layer and the light emitting layer. In the plan view, the first external connection portion includes a plurality of first portions located between the exposed portions in a first direction, and arrayed in the first direction, with a number of the first portions disposed between adjacent ones of the exposed portions being two or more, and a plurality of second portions not located between the exposed portions in the first direction, and arrayed in the first direction. Each of the second portions is different in shape or size from each of the first portions.Type: ApplicationFiled: February 3, 2022Publication date: August 4, 2022Inventors: Naoto FURUHA, Hiroki FUKUTA

Patent number: 11374151Abstract: A light-emitting device includes a semiconductor stacked body having first and second semiconductor layers. The second semiconductor layer includes conductive portions contacting a second conductive layer and having island configurations. The conductive portions are disposed in a first region, a second region, a third region, and a fourth region. The first region is positioned at a periphery of a first corner of the semiconductor stacked body. The second region is positioned at a periphery of a second corner of the semiconductor stacked body. The third region is positioned at a periphery of a third corner of the semiconductor stacked body. The fourth region is positioned at a periphery of a fourth corner of the semiconductor stacked body. A density of the conductive portions disposed in the first region is greater than densities of the conductive portions disposed in the second region, the third region, and the fourth region.Type: GrantFiled: July 13, 2020Date of Patent: June 28, 2022Assignee: NICHIA CORPORATIONInventor: Naoto Furuha
