Abstract

A direct-type back light module comprising a baseboard, pluralities of point-light-sources, and a mixing-light board is disclosed. The baseboard has pluralities of point-light-source disposal holes. The point-light-sources are disposed on the baseboard. The luminescent points of the point-light-sources are inside the point-light-source disposal holes. The mixing-light board is disposed upon the baseboard. The surface of the mixing-light board facing the point-light-source disposal holes has pluralities of protruding-reflective parts. The positions of the protruding-reflective parts are corresponding to the point-light-source disposal holes. The surface of the baseboard that facing the mixing-light board, the wall of the point-light-source disposal holes and the surfaces of the protruding-reflective parts have reflectivity. Otherwise, pluralities of diffusing means can be disposed upon the point-light-sources in the point-light-source disposal hole respectively. Besides, the diffusing means can be used without disposing the mixing-light board in the direct-type back light module.
