Abstract
A method for manufacturing a wavelength conversion member, includes: providing a wavelength conversion layer having a phosphor-containing portion and a light reflecting portion surrounding the phosphor-containing portion, and the wavelength conversion layer having an upper surface, a bottom surface and at least one side surface; forming a light-blocking film on the upper surface of the wavelength conversion layer; and removing a part of the light-blocking film by laser processing to expose at least a part of the phosphor-containing portion from the light-blocking film.
