    摘要: In order to suppress the chromaticity shift and corrosion associated with the deterioration of a sulfide phosphor particle, this phosphor sheet is produced using a phosphor particle-containing resin composition which comprises: covered phosphor particles; polymerizable compound; and a polymerization initiator. The covered phosphor particles are obtained by covering phosphor particles with silicon dioxide films, wherein among the phosphor particles, at least sulfide phosphor particles are covered with silicon dioxide films that contain a metal oxide powder. Thus, the phosphor sheet can be inhibited from emitting a sulfur-based gas, and exhibits a minimized chromaticity shift, even when the phosphor sheet is present in such a manner that the edge of the phosphor layer of the sheet is in an exposed state.

    摘要: Provided is a partial drive-type light source device including an excitation light source that is formed from a plurality of light-emitting elements and is partially drivable, a phosphor sheet disposed at a position separated from the excitation light source and containing a phosphor that converts at least part of a wavelength region of incident light from the excitation light source and releases emitted light in a wavelength region differing from the incident light, and a wavelength-selective reflection film that is disposed between the excitation light source and the phosphor sheet and that transmits at least part of light in the wavelength region of the incident light from the excitation light source and reflects at least part of light in the wavelength region of the emitted light from the phosphor sheet.

    摘要: 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.

    摘要: Disclosed are a phosphor sheet capable for converting light from LEDs into white light, a white light source device including the phosphor sheet, and a display device including the white light source device. The disclosed phosphor sheet includes a phosphor layer containing at least a phosphor and a resin; and a pair of transparent substrates sandwiching the phosphor layer. The phosphor sheet comprises a coloring material having an absorption maximum wavelength of at least one of from 480 nm to 510 nm or from 570 nm to 620 nm. The coloring material is contained in the phosphor layer. The transparent substrates are adhered to both surfaces of the phosphor layer. the phosphor layer has a thickness of 20 μm to 200 μm. An indicator of the usage amount of the coloring material defined by the following formula is 0.003 to 0.028: (indicator of the usage amount of the coloring material)=((blending amount of the coloring material in the phosphor layer)/(blending amount of a resin in the phosphor layer))×(the thickness of the phosphor layer (μm)).
