<P>PROBLEM TO BE SOLVED: To provide a light emitting device capable of realizing high luminance by suppressing absorption loss at a light scattering material. <P>SOLUTION: Light scattering particles 50 each having a diameter smaller than the wavelength of an LED element 2 are mixed into epoxy resin 5 to seal the LED element 2 , so that absorption loss of blue light radiated from the LED element 2 by the light scattering particles 50 is decreased to enhance luminance. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
