A light emitting device has a light emitting element portion that radiates
light with a predetermined wavelength, and a wavelength conversion
portion that surrounds a phosphor to be excited by the light with the
predetermined wavelength with a transparent and non-moisture permeability
material in the form of laminae. Further, a light emitting device has a
plurality of LED elements disposed on a same plane, and a wavelength
conversion portion that comprises a flat transparent base member that is
disposed opposite to the plurality of LED elements and a phosphor layer
that is of a phosphor to be excited by light emitted from the LED element
and is formed like a film on the base member. The phosphor layer includes
part with no phosphor in plane.
