Abstract

An assembling structure of a backlight module for containing and fabricating components of the backlight module comprises following components. A frame has a first edge and a second edge, wherein on outer surfaces of the first edge first hooks are fabricated and protruding outwardly, and on outer surfaces of the second edge first holes are formed. A bezel has a first sidewall and a second sidewall, wherein on the first sidewall second holes are formed, and on outer surfaces of the second sidewall second hooks are formed and protruding outwardly. When the frame is mounted onto the bezel, the first edge is disposed onto inside surfaces of the first sidewall, and the first hooks are inserted and engaged in the second holes for fastening the frame and bezel, simultaneously the second edge is disposed onto outside surfaces of the second sidewall, and the second hooks are inserted and engaged in the first holes for fastening the frame and the bezel.
