Abstract
Provided is a phosphor sheet that, despite its simplified structure, is capable of preventing deterioration in phosphors. In one of embodiments, the phosphor sheet includes moisture vapor barrier films 12 and 13 and a phosphor layer 11 that is sandwiched between the moisture vapor barrier films 12 and 13 and that includes a sulfide-based phosphor. Each of the moisture vapor barrier films 12 and 13 has an edge portion that is sealed by a cover member 14. The above structure prevents moisture vapor from entering the phosphor layer 11 from the edge portions of the moisture vapor barrier films 12 and 13, and accordingly, prevents deterioration in the phosphor(s) included in the phosphor layer 11.
