Abstract:
A light-emitting device comprising a package comprising a light-emitting element comprising a first surface and a second surface opposite to the first surface, a first light-transmissive member arranged on the second surface of the light-emitting element, paired electrodes at the first surface of the light-emitting element, and a first covering member covering the light-emitting element such that the paired electrodes are exposed from the first covering member. The light-emitting device further comprises a light-guiding plate on which the package is placed, and a second covering member arranged on the light-guiding plate and covering laterally the package. The light-emitting device further comprises paired wirings continuously covering the paired electrodes exposed and the first covering members and being connected to the paired electrodes respectively. The paired wirings are formed by irradiation of laser light on a metal paste layer continuously covering the paired electrodes and the first covering member to remove the metal paste layer between the paired electrodes, the metal paste layer comprising a mixture of a resin and metal powder.
