发明名称 LIGHT EMITTING DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide a light emitting device which is excellent in emission efficiency and color reproducibility as a backlight source. <P>SOLUTION: A yellow fluorescent body 7A which generates yellow light by the excitation of blue light emitted from an LED device 2, and a green fluorescent body 7B which generates an yellow color to a yellow-green spectrum by the excitation of blue light, are dispersedly mixed into a sealing resin 7 for the formation a light emitting body, so that the light emitting body is capable of expanding its color gamut in comparison with a white color obtained resting on a complementary relation between a blue color and an yellow color and improved in emission efficiency and color reproducibility. When the light emitting device 1 is used as a backlight source, an NTSC ratio can be improved, and when images of a television or a movie are reproduced, the images excellent and bright in image quality can be obtained. <P>COPYRIGHT: (C)2007,JPO&INPIT
