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 filmsandand a phosphor layerthat is sandwiched between the moisture vapor barrier filmsandand that includes a sulfide-based phosphor. Each of the moisture vapor barrier filmsandhas an edge portion that is sealed by a cover member. The above structure prevents moisture vapor from entering the phosphor layerfrom the edge portions of the moisture vapor barrier filmsand, and accordingly, prevents deterioration in the phosphor(s) included in the phosphor layer
