<P>PROBLEM TO BE SOLVED: To provide a light-emitting element having high luminance and high color rendering properties, and to provide an image display apparatus and an illuminator each of which uses the light-emitting element as a light source. <P>SOLUTION: In the light-emitting element including a phosphor to be a wavelength converting material and a semiconductor light-emitting element for emitting visible light, the phosphor is a phosphor of at least one or more selected from a group composed of oxide, oxynitride and nitride, a mixture of two or more sorts of phosphors, wherein luminous efficiency at room temperature when the phosphors are excited by visible light from the semiconductor light-emitting element is 35% and more, is used. The mixture includes: a first phosphor; and a second phosphor capable of absorbing light emitted from the first phosphor and different from the first phosphor, wherein the first phosphor is contained in the mixture of the phosphors at the rate of 85 wt.% and more. <P>COPYRIGHT: (C)2011,JPO&INPIT |
