A phosphor sheet capable of preventing deterioration of a phosphor with an easy configuration is provided. And a phosphor layer (11) sandwiched between the vapor barrier films (12, 13) and containing a sulfide phosphor, wherein the end portions of the vapor barrier films (12, 13) (14). This makes it possible to prevent water vapor from entering the phosphor layer 11 from the ends of the water vapor barrier films 12 and 13 and to prevent deterioration of the phosphor in the phosphor layer 11.
