The invention provides a display device, comprising a display panel and a backlight module. The backlight module comprises a light source, a fluorescence film and a multi-hole layer. The fluorescence film is arranged on the back side of the display panel and comprises a plurality of quantum dot phosphors. The multi-hole layer is arranged between the fluorescence film and the display panel, covers the fluorescence film, and comprises a plurality of holes. The multi-hole layer is arranged between the fluorescence film and the display panel, or the fluorescence film is internally provided with the multi-hole layer, thereby improving the recycling efficiency of the first light ray generated by the light source, and furthermore increasing the number and brightness of the second light ray generated by the light source, and reducing the manufacturing cost of the backlight module.
