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.

Abstract: 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.

Abstract: A transmission cable includes multiple signal lines formed on one side of an insulation layer and a ground line between the signal lines. The ground line is electrically connected to a shield layer formed on a back surface side of the insulation layer and to a noise suppressing layer having a high electric resistance value than the shield layer via a metal bump embedded and formed in the insulation layer. The noise suppressing layer has a function to suppress an unwanted emission and/or a noise and has a function as an etching barrier layer serving as an etching stopper in a step for forming the metal bump. Thus, the transmission cable can suppress an increase of an electric resistance and a connection resistance between the ground line and the shield layer.
