Abstract
A backlight module without a light guiding plate and a diffusing plate is disclosed, in which a reflective layer having a light scattering structure is first disposed on a backplate and then at least a reflective mirror is provided on the reflective layer of the backplate. Further, a transparent plate is disposed on the at least reflective mirror. The backplate, the at least a reflective mirror, the reflective layer and the transparent plate form an enclosed space and thus the backlight module without a light guiding plate and a diffusing plate is completed. In another form of the backlight module without a light guiding plate and a diffusing plate, the light scattered structure is formed directly on the backplate. When a light-emitting unit emits a light source, the light source is uniformly given off through the light scattering structure, promoting use efficiency of the light source.
