Abstract:
1. A wavelength conversion sheet filled with a phosphor, the sheet comprising a layer formed from a heat-curable resin composition, which comprises 100 parts by mass of a resin component and 200 to 2,000 parts by mass of a particulate phosphor in which a proportion of particles having a sphericity of 0.7 to 1.0 is not less than 60% of all particles, and which exists in a plastic solid or semisolid state in an uncured state at normal temperature, wherein: an average particle diameter of the phosphor is not more than 60% of a thickness of the layer formed from the heat-curable resin composition; and a maximum particle diameter of the phosphor is not more than 90% of the thickness of the layer formed from the heat-curable resin composition.
