<P>PROBLEM TO BE SOLVED: To provide a light-emitting diode module in which a light guide plate for color mixture having a recessed part for housing a light-emitting diode element and a light diffusion sheet arranged on a surface opposed to the recessed part and a sub-mount substrate mounting the light-emitting diode element are sealed by resin, and which is improved in reliability as a light source by suppressing color unevenness caused by interface separation between the sealed resin and the light guide plate for color mixture. <P>SOLUTION: The light-emitting diode element uses a transparent soft resin as a sealing resin and a fine space is provided between the sealing resin and the light guide plate for color mixture. Furthermore, the recessed part of the light guide plate for color mixture is made a hemisphere. <P>COPYRIGHT: (C)2008,JPO&INPIT |
