Abstract: A light emitting device includes a substrate, light emitting elements, light transmissive members, an underfill, and a cover member. The light emitting elements are mounted on the substrate. The light transmissive members are each disposed on an upper surface of each of the light emitting elements. The underfill covers an upper surface of the substrate, lateral surfaces of the light emitting elements, and lateral surfaces of the light transmissive members between the light transmissive members. The cover member covers an upper surface of the underfill and has a hardness greater than a hardness of the underfill.

Abstract: A light emitting device includes light emitting elements having light extraction faces, respectively. A light transmissive member includes a lower face facing the light extraction faces, an upper face opposite to the lower face in a height direction, and first to fourth side faces that are connected to the lower face and the upper face. An area of the lower face is larger than a sum of areas of the light extraction faces. An area of the upper face is smaller than the area of the lower face. The second side face is substantially parallel to the first side face. The third side face and the fourth side face are provided between the first side face and the second side face and opposite to each other. The third side face and the fourth side face approach as approaching from the lower face to the upper face in the height direction.

Abstract: A light emitting device includes a light emitting element, a light-transmissive member, a covering member, and a base member. The light-transmissive member has a flange on a lateral surface thereof in such a manner as to continue from a periphery of an upper surface to a periphery of a lower surface of the light-transmissive member and to be positioned outside the upper surface of the light-transmissive member and an upper surface of the light emitting element in plan view. The flange has a thin portion at an inner side than the outer edge side of the flange. The thin portion has a thickness smaller than a thickness of the outer edge side of the flange.

Abstract: A method of manufacturing a light emitting device includes: mounting light emitting elements on a collective substrate; arranging a first protruding member surrounding the light emitting elements; arranging a second protruding member between the light emitting elements; forming a cover member covering an upper end of the second protruding member, a lateral surface of each of the light emitting elements in a region surrounded by the first protruding member; and singulating the light emitting devices by cutting the cover member, the second protruding member, and the collective substrate at a portion including the second protruding member. The second protruding member is harder than the cover member. An upper end of the second protruding member is located lower than that of the first protruding member but higher than the upper surface of each of the light emitting elements.
