Abstract
A planar light-emitting module includes a planar substrate applied with a reflection film, a light-emitting element mounted on the reflection film side of the substrate, a first transparent resin layer disposed to encapsulate at least the light-emitting element, and a second transparent resin layer disposed to sandwich an air layer between the second transparent resin layer and the first transparent resin layer. A phosphor for converting the wavelength of light radiated from the light-emitting element is disposed by dispersion in the first and second transparent resin layers and the phosphor is selected such that when the second transparent resin layer is viewed from the outside, pseudo-white light is observed.
