A light emitting device includes: a substrate; a light emitting element; a wavelength conversion layer; and a wall surrounding the wavelength conversion layer, having an opening portion exposing at least a part of a top surface of the wavelength conversion layer, and containing a light reflective material. The surface of the wall includes a top surface provided at a higher position than the top surface of the wavelength conversion layer, and an inner surface forming the opening portion. The wall includes a first portion surrounding the wavelength conversion layer, and a second portion provided over the first portion and surrounding the first portion. The opening portion is hollow. An angle of a corner portion between the top surface and the inner surface of the wall is in a range of 90 degrees or greater and less than 180 degrees.

Light emitting device and method of manufacturing light emitting device

A light-emitting apparatus includes a package including a support having a central section and a peripheral section around the central section. The central section is raised upwardly from the peripheral section, providing a pedestal for supporting a light-emitting device. A light-emitting device secured on an upper surface of the pedestal and has electrodes. Electrically conductive members are provided on a peripheral region of the package and electrically connected to the electrodes of the light-emitting device. A color conversion layer covers the light-emitting device. A light-transmitting member is formed in the package, sealing at least the light-emitting device together with the color conversion layer. The pedestal has its side surface at least partially exposed from the color conversion layer.
