Abstract: A backlight module and a display device having the backlight module are provided. The backlight module includes a planar light source having a light-emitting surface; a fluorescent film covering the light-emitting surface of the planar light source; a supporting layer disposed on the fluorescent film, wherein the supporting layer being a transparent gel layer; and a diffusing plate covering the supporting layer. Under the premise of ensuring higher light efficiency, the backlight module and the display device having the backlight module of the present invention reduce the number of the layers of the diffusing plate in the backlight module and increase the light transmittance. Thereby a better light mixing effect, a uniform light mixing realized by a higher light-emitting effect, and a thinner backlight module are achieved.
