Abstract
A face light source module structure including more than one light sources and a light guiding board. One face of the light guiding board adjacent to the light sources is defined as an incoming face. One face of the light guiding board opposite to the incoming face is defined as a first reflective face plated with a mirror face coating. One face of the light guiding board adjacent to the liquid crystal module is defined as an outgoing face. The face opposite to the outgoing face is defined as a second reflective face. The outgoing face and the second reflective face are respectively evaporated with two anti-reflection coatings. The anti-reflection coating of the outgoing face has a leakage design. After going into the light guiding board, the light of the light sources is totally reflected to project through the leakage design of the outgoing face toward the liquid crystal module.
