<P>PROBLEM TO BE SOLVED: To provide an LED package and a display device which have excellent light extraction efficiency and a sufficient view angle. <P>SOLUTION: An LED element mounted surface 11D is made close to the optical shape surface 15A of an elliptically formed lens 15 and is disposed above the surface 15A in a (z) direction, and a filler 2 is injected below a reflector tip surface 11B in the (z) direction to seal the LED package 1. Consequently, the light extraction efficiency is improved as compared with the conventional LED package. Further, an interface 11C between a case 11 and the lens 15 is provided below the LED element mounted surface 11D in the (z) direction, and the filler 2 is injected above the interface 11C in the (z) direction to seal the LED package 1. Consequently, intrusion of a foreign substance from the interface 11C can be prevented and the display device having the LED package 1 can withstand the outdoor use. <P>COPYRIGHT: (C)2009,JPO&INPIT |
