A phosphor protection film for protecting phosphors contained in a phosphor layer. The phosphor protection film includes a functional layer, a bulking layer that has a single-layer structure or a laminated structure, and a first vapor deposited layer (gas barrier layer) that has gas barrier properties in this order from outside to inside. The clearance between the functional layer and the first vapor deposited layer in the thickness direction of the phosphor protection film is 45 to 280 &#x3bc;m.
