Abstract
The present disclosure relates to a backlight module, a method for manufacturing the backlight module, and a display device. The backlight module includes a substrate, a plurality of LED chips, and a first film having a plurality of channels. Each channel is filled with a channel filling portion. A refractive index n1 of the first film is smaller than a refractive index of the channel filling portion is n2. The first film has a first region and second region. Channels in the first region are astigmatism holes for diverging the light having a high intensity and channels in the second region are light-converging holes for converging the light having a low intensity, thereby alleviating or eliminating the starry phenomenon.
