Abstract:
A method for manufacturing a light-emitting device includes preparing an intermediate product; the product includes a light-emitting element provided with paired electrodes at a first surface and a first covering member covering the light-emitting element such that portions of surfaces of the paired electrodes are exposed. A metal paste layer is formed, continuously covering the exposed portion of the paired electrodes and the first covering member. Paired wirings are formed for preventing the paired electrodes from being short-circuited. The metal paste layer on the paired electrodes and the metal paste layer on the first covering member are irradiated with laser light to remove the metal paste layer between the paired electrodes and a portion of the metal paste layer on the first covering member.
