Patent ID: 7960909

Claim:
A light-emitting device comprising: a support; a light-emitting part; and a fluorescent layer consisting essentially of a matrix polymer including an organic fluorescent material and an inorganic fluorescent material, wherein the fluorescent layer in the matrix polymer has a concentration of the inorganic fluorescent material whose abundance ratio is decreased toward an uppermost surface from a lowermost surface of the fluorescent layer along a thickness direction of the fluorescent layer, and the fluorescent layer in the matrix polymer has a concentration of the organic fluorescent material whose abundance ratio is decreased toward the lowermost surface from the uppermost surface of the fluorescent layer along a thickness direction of the fluorescent layer, wherein a concentration of the organic fluorescent material in a region of the fluorescent layer within 50 μm from the lowermost surface of the fluorescent layer is 20% or less, excluding 0%, relative to a concentration of the organic fluorescent material in the uppermost surface of the fluorescent layer.
