Claim:
1. A double-layered backlight module comprising: a supporting plate having a supporting surface and a plurality of through holes formed on the supporting surface; a plurality of light sources disposed on the supporting surface; a first optical modulation film disposed at one side of the supporting plate where the plurality of light sources is located, a first interlayer formed between the first optical modulation film and the supporting surface, wherein the first optical modulation film comprises: a first reflective surface formed at one side of the first optical modulation film facing the plurality of light sources; and a plurality of first light exiting holes penetrating the first optical modulation film; a first diffusing plate disposed at one side of the first optical modulation film opposite to the supporting plate; and a second diffusing plate disposed at one side of the supporting plate opposite to the supporting surface, wherein a part of light generated from the plurality of light sources is reflected by the first reflective surface and the supporting surface in the first interlayer and arrives at the first diffusing plate via the plurality of first light exiting holes; another part of light is reflected by the first reflective surface and arrives at the second diffusing plate via the plurality of through holes.
