Abstract
A method of manufacturing a light emitting device includes a first step of mounting a light emitting element on a substrate having a conductor wiring and electrically connecting the light emitting element with the conductor wiring, a second step of disposing a light reflecting resin which reflects light from the light emitting element to surround the light emitting element, and a third step of disposing a sealing member after hardening the light reflecting resin to cover the light emitting element.
Claims15
A method of manufacturing a light emitting device comprising:
- a first step of mounting a light emitting element on a substrate having a conductor wiring and electrically connecting the light emitting element with the conductor wiring, the substrate including an exposed region in which the conductor wiring is not arranged,
- a second step of disposing a light reflecting resin to surround the light emitting element in order to reflect light from the light emitting element, and to cover the exposed region of the substrate by the light reflecting resin so that the substrate is not exposed within a region surrounded by the light reflecting resin;
- a third step of disposing a sealing member to cover the light emitting element, after hardening the light reflecting resin;
- and
- a fourth step of dividing the substrate along a dividing position that is spaced apart from a region in which the light reflecting resin has been disposed in the second step, after hardening the sealing member disposed in the third step, wherein
- the light reflecting resin is disposed in the second step by discharging a liquid resin from a resin discharge device.
