Abstract: A light-emitting device includes: a package defining a recess; a light-emitting element disposed on a bottom surface of the recess; and a sealing member disposed in the recess so as to cover the light-emitting element. The sealing member includes a filler-containing layer which contains a filler and covers the light-emitting element, and a light-transmissive layer disposed on the filler-containing layer. The recess is further defined by a lateral surface having a stepped portion between the bottom surface of the recess and an opening of the recess. The light-transmissive layer covers the stepped portion. An upper surface of the light-transmissive layer is downwardly recessed.

Abstract: A method of manufacturing a light-emitting device includes: providing a first intermediate structure including a substrate, light-emitting elements arrayed in a first direction, a protective element, and light-transmissive members; forming a resin wall including first and second walls extending in the first direction, and third and fourth walls, a first distance between the first wall and the light-emitting elements being larger than a second distance between the third or fourth wall and a corresponding one of light-emitting elements; applying a first resin to a first region between the first wall and the light-emitting elements in which the protective element is disposed, resulting in forming a first recess in the first region and a second recess in a second region between the second wall and the light-emitting elements; and forming a covering member by applying a second resin to the first and second recesses and curing the first and second resins.

Abstract: A method for manufacturing a light emitting device includes: providing a substrate including a placement region for placing a light emitting element on a top surface; mounting the light emitting element in the placement region; and forming a frame body surrounding the placement region on the substrate. The step of forming the frame body is performed by arranging a first frame body and second frame body on the substrate to surround the placement region. The second frame body have a larger diameter than the first frame body, and have the same thickness as the first frame body.

Abstract: A light emitting device includes a base member; a light emitting element mounted on the base member; a light-transmissive member that covers an upper surface of the light emitting element, and is substantially rectangular in a plan view; and a light reflecting member that covers a lateral surface of the light-transmissive member, the light reflecting member having a substantially rectangular frame shape in a plan view. A width of the light reflecting member is smaller along a short side of the light-transmissive member than along a long side of the light-transmissive member. A height of the light reflecting member is smaller along the short side of the light-transmissive member than along the long side of the light-transmissive member at a position separated from an outer edge of the light reflecting member by a predetermined distance.

Abstract: A method of manufacturing a light emitting device includes: providing a first intermediate body including a substrate, first bonding members, a second bonding member, a light emitting element, a protecting element, a light transmissive member bonded to the light emitting element, and a light-shielding frame surrounding the light transmissive member in a top view, a portion of an outer periphery of the light-shielding frame being located above the protecting element such that at least a portion of the protecting element is exposed from the light-shielding frame in the top view; disposing a first resin between the light emitting element and the substrate by applying the first resin on the substrate in a region outside of the portion of the protecting element such that the first resin moves toward the light emitting element along the protecting element; and curing the first resin to obtain a first cover member.

Abstract: A light-emitting device includes: a package defining a recess; a light-emitting element mounted on surface that defines a bottom of the recess; and a sealing member disposed in the recess so as to cover the light-emitting element and made of a light-transmissive resin that contains a filler with an average particle diameter of 200 nm or more and 500 nm or less. The sealing member comprises a filler-containing layer, which contains the filler, and a light-transmissive layer that are layered in an order from a bottom side of the recess. The filler-containing layer has a thickness of equal to or larger than a height of the light-emitting element.
