Abstract:
A light emitting device includes: a light emitting element; a light-transmissive member including a first lower surface, an outer periphery of which being located on an outer side of the light extraction surface in a plan view, an upper surface having a greater area than an area of the first lower surface, a first lateral surface connected to the upper surface, a second lateral surface positioned on an inner side of the first lateral surface and connected to the first lower surface, and a second lower surface connected to the first and second lateral surfaces; a light guiding member covering at least a portion of a lateral surface of the light emitting element and at least a portion of the second lateral surface and the second lower surface; and a covering member covering the first lateral surface and a lateral surface of the light guiding member.
