Abstract

A method for manufacturing a light-emitting device, comprising: forming, over a substrate, a plurality of multilayered light-emitting structures each including a first electrode, a light-emitting layer, and a second electrode; forming, in the substrate, a plurality of grooves that surround the multilayered light-emitting structures individually; forming, over the substrate, a sealing film that covers the multilayered light-emitting structures and the grooves; and separating the multilayered light-emitting structures from one another after forming the sealing film, by cutting the substrate such that, in each groove, part of the sealing film covering a given inner side surface of the groove remains, the given inner side surface being adjacent to any of the multilayered light-emitting structures.
