Abstract
The present disclosure discloses a backlight module and a display device. The light emission direction of at least one of the lamp source and the fluorescent film is provided with a diffusely reflecting layer. The diffusely reflecting layer arranged above the lamp source diffusely reflects pump light emitted from the lamp source, which may enhance uniformity of the pump light. The diffusely reflecting layer arranged above the fluorescent film scatters light emitted from the fluorescent film, scatters the light and distributes the light to a larger range, which may improve light mixing uniformity and improve the uniformity of light emission brightness.
