Abstract

Provided are a white light-emitting device and a method of fabricating the same. The white light-emitting device includes a blue light-emitting diode (LED), and a fluorescent substance layer conigured to absorb light emitted from the blue LED and emit light having a wavelength different from a wavelength of the absorbed light. Here, the blue LED includes a GaN-based semiconductor light-emitting layer and has a light-emission peak in a wavelength region of at least 410 nm and less than 460 nm, and the fluorescent substance layer has a blue fluorescent substance having a light-emission peak in a wavelength region of at least 460 nm and less than 500 nm, a green fluorescent substance having a light-emission peak in a wavelength region of at least 500 nm and less than 550 nm, a yellow fluorescent substance having a light-emission peak in a wavelength region of at least 550 nm and less than 600 nm, and a red fluorescent substance having a light-emission peak in a wavelength region of at least 600 nm and less than 660 nm. Thus, white light is emitted by mixing light emitted from the blue LED and blue, green, yellow and red lights emitted from the fluorescent substance layer.
