Abstract
The present invention embodiment provides a backlight module and a display module. The backlight module includes a light emitting assembly, a color conversion layer, and a reflection function layer. The reflection function layer at least includes a first sublayer and a second sublayer. A refractive index of the first sublayer is less than a refractive index of the second sublayer. A light emitted by the color conversion layer to the reflection function layer includes a first light. A product of a thickness of the first sublayer and the refractive index of the first sublayer is equal to an integer multiple of a half wavelength of first light.
