White light-emitting device and manufacturing method thereof, and backlight and liquid crystal display device using the same
摘要:
A white light-emitting device 1 includes a semiconductor light-emitting element 2 emitting ultraviolet light or violet light, and a light-emitting unit 10 which includes three or more kinds of visible light-emitting phosphors 9 and emits white light when excited by the light from the semiconductor light-emitting element 2. The emission spectrum of the light-emitting unit 10 has peaks in a blue region of not less than 440 nm nor more than 460 nm, a green region of not less than 510 nm nor more than 530 nm, and a red region of not less than 620 nm nor more than 640 nm, and the three or more kinds of visible light-emitting phosphors 9 are bound together with a binder in advance.
