<P>PROBLEM TO BE SOLVED: To achieve a method for manufacturing a light-emitting diode for preventing bubbles and cracks from occurring in a coating material composed of glass, namely an inorganic material. <P>SOLUTION: In the method for manufacturing a light-emitting diode 10 where an LED chip 16 is coated with a coating material 22 made of sol-gel glass having light transmission properties, a surface hardening retarder is added to a sol-gel glass material in a solution containing a solvent like a metal organic compound, water or methanol, the LED chip 16 is coated with the sol-gel glass material, and the sol-gel glass material is subjected to hydrolysis and polymerization reaction, thus forming a coating material 22 made of the sol-gel glass. As the surface hardening retarder, a solvent having a high boiling point or an organic polymer is used. <P>COPYRIGHT: (C)2010,JPO&INPIT |
