<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 water glass having light transmission properties, a surface hardening retarder is added to a water glass material in a solution comprising sodium solicate and water as a solvent, the LED chip 16 is coated with the water glass material, and water, namely a solvent, is evaporated for hardening, thus forming a coating material 22 made of the water 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 |
