20130161684 | LIGHT-EMITTING DEVICE AND MANUFACTURING METHOD THEREOF - A light-emitting device having a curved light-emitting surface is provided. Further, a highly-reliable light-emitting device is provided. A substrate with plasticity is used. A light-emitting element is formed over the substrate in a flat state. The substrate provided with the light-emitting element is curved and put on a surface of a support having a curved surface. Then, a protective layer for protecting the light-emitting element is formed in the same state. Thus, a light-emitting device having a curved light-emitting surface, such as a lighting device or a display device can be manufactured. | 06-27-2013 |
