Abstract: A light emitting device includes a base substrate having a recessed portion at a flat upper surface thereof. The recessed portion has an inner wall. A sealing member is provided in the recessed portion. The sealing member contains surface-treated particles, or particles coexisting with a dispersing agent. The particles have a particle diameter of 1 nm or more and 100 μm or less. The particles are made of an organic material or an inorganic material. The organic material and the inorganic material are free of a phosphor. The at least a part of an edge portion of the sealing member is a region located in the vicinity of an edge of the recessed portion which is a boundary between a surface of the inner wall and the flat upper surface. The at least one of the particles and aggregates of particles are unevenly distributed in the region.
