A liquid crystal display (LCD) module includes: a back light unit device having a) a lamp, b) a reflection sheet reflecting light from the lamp, c) a light guide positioned over the reflection sheet, the light guide having grooves at opposing sides, and d) a plurality of sheets located over the light guide, each sheet having a through hole corresponding to the grooves of the light guide; a liquid crystal panel located over the back light unit; a first frame located over the liquid crystal panel; a second frame having a) a main portion under the back light unit, b) first and second wall portion perpendicular to the main portion and disposed on sides of the main portion, and c) supporting portions extending outwardly from upsides of the first and second wall portions and parallel to the main portion, the supporting portion having first fastening means; and a fixing unit having a) pressing portions parallel to the supporting portions of the second frame, the pressing portions pressing down the grooves of the light guide, b) protrusions protruded upward from the pressing portions, the protrusions being inserted into the through holes of the plurality of sheets, and c) a connecting portion parallel to the supporting portion of the second frame, the connecting portion having a second fastening means fastening with the first fastening means of the second frame. Since the second frame is made from metal, heat transfer of the liquid crystal display module is better than in a conventional LCD module.
