Abstract:
It is an object of the present invention to provide a wavelength conversion member capable of appropriately performing color conversion compared to the prior arts and a light-emitting apparatus, a light-emitting element, a light source apparatus, and a display apparatus using the wavelength conversion member. A wavelength conversion member of the present invention includes a light incident surface, a light emission surface and a side face that connects between the light incident surface and the light emission surface, and includes a container provided with a storage space inside the side face, a wavelength conversion substance that fills the inside of the storage space and a colored layer formed on the side face.
