PROBLEM TO BE SOLVED: To improve the color reproducibility of a liquid crystal display device than before. A backlight device includes a blue LED 19 that emits blue light having an emission peak in a wavelength range of 440 nm to 460 nm, and a green phosphor that emits green light having an emission peak in a wavelength range of 500 nm to 595 nm. 21 and a red phosphor 22 that emits red light having an emission peak in a wavelength range of 600 nm to 690 nm, and a spectral radiant intensity in a wavelength range of 570 nm to 590 nm in a mixed color light of blue light, green light, and red light. And a filter component 23 to be reduced. [Selection] Figure 2 |
