Beschreibung
Zusammenfassung:	The invention discloses a backlight module which comprises a light source, a multilayer film and a wavelength conversion layer. The multilayer film is disposed on the light source. The wavelength conversion layer is disposed on a surface of the multilayer film opposite to the light source. The wavelength conversion layer converts a part of light from the light source into a plurality of colored lights including a first colored light and a second colored light. The wavelength value corresponding to the intensity peak value of the first color light is smaller than the wavelength value corresponding to the intensity peak value of the second color light. The multi-layer film has a reflection range with respect to wavelength, the multi-layer film reflects light with the wavelength falling within the reflection range, the reflection range of the multi-layer film comprises intensity peaks of the first colored light and the second colored light, and the penetration rate of the multi-layer film within the wavelength r
