Abstract: The present application provides a backlight module and a display device, including a light source component, a quantum dot component, and a wavelength-band-light-reflecting component being arranged in a stack. The wavelength-band-light-reflecting component reflects light emitted by the quantum dot component in a specific band range, so as to reduce full width at half maximum of the light. The present application reduces the full width at half maximum of monochromatic light by arranging the wavelength-band-light-reflecting component reflecting light in the specific band range, thereby increasing gamut of a display module.
