Abstract
A light-emitting device includes a support board including a first base with flexibility and having a region where a first metal film is formed, a connection board disposed on an upper surface of the support board and including a second base on which a second metal film is formed, a light-emitting element mounted on the connection board, and a conductive member in contact with the first metal film and with the second metal film.
Claims21
A light-emitting device comprising:
- a support board including a first base, the first base being flexible, the support board having a region where a first metal film is formed;
- a connection board disposed on an upper surface of the support board, the connection board including a second base on which a second metal film is formed;
- a light-emitting element mounted on the connection board;
- and
- a conductive member in contact with the first metal film and with the second metal film,
- wherein the conductive member directly connects from an upper surface of the second metal film to an upper surface of the first metal film.
