Abstract: A method for manufacturing a light-emitting device includes providing a transparent member having a protrusion formed at an upper surface of the transparent member. A first resin portion is placed on the protrusion in which the first resin portion has a solid form and is made from a first resin material of which the viscosity decreases when heated. A light-emitting element is placed on the first resin portion, the light-emitting element is caused to be self-aligned with respect to the protrusion by reducing a viscosity of the first resin portion by heating to a first temperature. The first resin portion is solidified by cooling.

Abstract: A light-emitting module includes a light-emitting element unit including a light-emitting element, a light-transmissive member covering a main light-emitting surface of the light-emitting element, and a first light-reflective member covering lateral surfaces of the light-emitting element; a light-transmissive light-guiding plate having a first main surface and a second main surface having a recess accommodating the light-emitting element unit; a second light-reflective member covering the second main surface and the light-emitting element unit; and a light-transmissive bonding member disposed in contact with inner lateral surfaces of the recess and outer lateral surfaces of the light-emitting element unit. At least a portion of the first light-reflective member is located outside the recess in a cross-sectional view, and is in contact with the light-transmissive bonding member. The light-transmissive bonding member has an inclined surface forming an acute angle with a corresponding outer lateral surface of the first light-reflective member.

Abstract: A light emitting device includes: a rectangular substrate, a light emitting element, a reflective member disposed at one or more lateral sides of the light emitting element while being away from therefrom, a light guide member, and a light transmissive member on the light guide member. The reflective member includes one or more first reflective members opposing lateral faces of the light emitting element, and a second reflective member outside the first reflective member. The first reflective members have inner lateral faces opposing each other each having an oblique or curved portion slanted so that a distance therebetween increases towards the light transmissive member from a side close to the substrate. The second reflective member covers outer lateral faces of the light transmissive member and the first reflective members, and an upper face of the second reflective member is flush with an upper face of the light transmissive member.
