Abstract

There is provided is a display device capable of suppressing deterioration of the color conversion layer which converts one color light into another color light, and realizing favorable handling and a display device using the color conversion layer, and a color conversion sheet. A phosphor sheetis, for example, arranged immediately above a light source such as a blue light emitting diode, and obtained by sealing a phosphor layer, which converts a part of blue light into another color light, by sealing sheetsA andB. The sealing sheetsA andB are bonded with the phosphor layerin between by a first bonding layerand a second bonding layer. Since the phosphor layeris sealed by the sealing sheetsA andB including a water vapor barrier layerheld between resin sheetsA andB, water vapor is prevented from entering into the phosphor layer, and a chemical reaction is less likely to be generated between the phosphor layerand the water vapor barrier layer
