<P>PROBLEM TO BE SOLVED: To provide a light emitting device in which light emitted from a light emitting element can be wavelength-converted to obtain the light emission of a desirable color and a sufficient light fetching efficiency is provided. <P>SOLUTION: The light emitting device is provided with a light emitting element 1, and a wavelength conversion layer 2 which contains a wavelength conversion substance of wavelength-converting light emitted from this light emitting element 1. The wavelength conversion layer 2 has a wavelength conversion division 3 containing the wavelength conversion substance and a transparent division 4 which has the smaller content of the wavelength conversion substance than in the wavelength conversion division 3. For this reason, the light after having transmitted the wavelength conversion layer 2 contains the wavelength converted one with the wavelength conversion substance in the wavelength conversion division 3, and light having a different hue from a light color emitted from the light emitting element 1 is emitted from the light emitting device A. Further, in the transparent division 4, it is harder for light to scatter due to the wavelength conversion substance than when transmitting the wavelength conversion division 3, and an amount of light which transmits the wavelength conversion layer 2 can be enhanced. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
