发明名称 LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide a light-emitting device and an electronic apparatus by which the uniformity of luminance is improved and the occurrence of color unevenness is suppressed as much as possible. <P>SOLUTION: The light-emitting device 4 includes an LED 42, a base material 41 mounted with the LED 42 and a fluorescent substance 44 which is excited by light emitted from the LED 42 to radiate light having a wavelength different from that of the LED 42. The light-emitting device 4 emits light from the LED 42 and the light radiated from the fluorescent substance 44 toward a light guide plate 31 which guides light in a predetermined direction. The fluorescent substance 44 has pin holes 44A which are formed in a direction toward the LED 42 from the external surface facing the light guide plate 31 in a predetermined region including the vicinity of the center of the fluorescent substance 44. <P>COPYRIGHT: (C)2009,JPO&INPIT
