Abstract
A method of manufacturing a light emitting device, the method includes: preparing an intermediate structure including a supporter, a plurality of light emitting elements arranged on the supporter, a covering layer arranged on the supporter and surrounding the light emitting elements, and wiring electrodes each arranged on and straddling the covering layer and a corresponding one of the light emitting elements: preparing a board including light-reflective resin arranged on a surface of the board; pressing the intermediate structure against the light-reflective resin arranged on the board, with the wiring electrodes facing the light-reflective resin; curing the light-reflective resin to form a light-reflective resin layer; and removing the supporter.

A method of manufacturing a light emitting device, the method comprising:
- preparing an intermediate structure including
- a supporter having a first surface and a second surface opposite to the first surface,
- a plurality of light emitting elements arranged on the supporter, each of the light emitting elements having a side surface, the plurality of light emitting elements including a first light emitting element and a second light emitting element,
- a covering layer continuously and directly covering the first surface of the supporter, the side surface of the first light emitting element and the side surface of the second light emitting element, the covering layer having a top surface, and
- wiring electrodes each arranged on and straddling the top surface of the covering layer and a corresponding one of the light emitting elements;
