Abstract: A light-emitting diode (LED) and a backlight-type display device are provided. The light-emitting diode includes: a multi-color light emitting chip, an emission spectrum thereof including a first peak in a wavelength range of a first primary-color light and a second peak in a wavelength range of a second primary-color light, and an absolute value of a wavelength difference between the first and second peaks being greater than 50 nm; and a phosphor-containing layer, disposed over the multi-color light emitting chip and used to be excited to emit a third primary-color light. Owing to the LED adopts the multi-color light emitting chip which has the first and second peaks in different wavelength ranges and the absolute valve of the wavelength difference is greater than 50 nm, RGB three-primary-color lights can be outputted by adopting a single-color light phosphor powder with relatively high reliability. The backlight-type display device can obtain a high NTSC level.
