Title:
PHOSPHOR SHEET
Document Type and Number:
Japanese Patent JP2014024918
Kind Code:
A
Abstract:
To suppress a chromaticity shift and corrosion that are caused by deterioration of a sulfide phosphor.
A phosphor-containing resin composition used in the present invention includes: a coated phosphor in which a phosphor is coated with a silicon dioxide film; a polymerizable compound; and a polymerization initiator. In this composition, at least a sulfide phosphor 2 among phosphors is coated with a silicon dioxide film 4 including a metal oxide powder 3. Using the composition enables sulfur gas emissions to be prevented, and a chromaticity shift to be reduced even when a phosphor sheet with ends of a phosphor layer exposed is used.
