The invention discloses a light source assembly used for a backlight module. The light source assembly comprises a substrate and an LED chip packaged on the substrate. An optical conversion part is arranged on the LED chip and used for converting monochromatic light emitted by the LED chip into white light. The light source assembly is characterized in that a filtering membrane set is arranged on the optical conversion part and used for shrinking wavelength ranges corresponding to red light, green light and blue light in the white light. The invention further discloses the backlight module comprising the light source assembly and a liquid crystal displayer. The light source assembly can shrink the wavelength ranges corresponding to the red light, green light and blue light in the generated white light, without changing band-pass wavelength ranges of all color resistors in a colorful filtering substrate, the color purity of all pixels can be improved, and then the color gamut is increased.
