Abstract: A light dispersing device mainly includes plural light transmissive plates and plural luminous bodies. Each light transmissive plate has at least two inclined sections, a middle section, and two extending sections. The inclined sections extend respectively from two ends of the middle section outwardly and inclinedly, and further connect to extending sections. The middle section has a first surface and a second surface. At least one of the first and the second surfaces is formed with a light reducing layer. The luminous bodies face to middle sections of corresponding light transmissive plates respectively. As such, linear light sources of each luminous are blocked and weakened by the light reducing layer, and a part of the light sources are reflected simultaneously along the inclined sections to extending sections. Thus the light sources are evenly dispersed outwardly.
