<P>PROBLEM TO BE SOLVED: To provide a light emitting device with high reliability, long life and inexpensive manufacturing cost since a request is strong for long life, high reliability, low cost and energy saving to the light emitting device using an LED element. <P>SOLUTION: In the light emitting device, the LED element is mounted on the substrate, a resin layer or a glass layer to which phosphor is mixed is formed at a periphery of the LED element, luminescence of the LED element is wavelength-converted and light is emitted. The substrate is the inorganic material substrate. The LED element is flip chip-mounted on the inorganic material substrate. The periphery of the LED element is covered with a wavelength conversion layer formed of the resin layer or the glass layer to which phosphor is mixed. A glass lid is put on a periphery of an LED element mounting region on the inorganic material substrate so as to seal it. <P>COPYRIGHT: (C)2010,JPO&INPIT |
