In the packaging of an LCD module within a small and lightweight case, the case comprising a front case and a rear case, a recess with a predetermined depth, formed at the edge of the bottom side of the LCD module, is combined with a boss formed at the case, and a recess with a predetermined depth, formed at the edge of its surface, is fastened to a fastening means for securing the LCD module, thereby minimizing the difference between the areas of the LCD module and the case and further reducing the number of processes required for combining the LCD module with the case. In addition, the recess formed at the surface edge of the LCD module is combined with a fastening hook formed at the rear case so that the LCD module can be secured to the rear case and to the front case without any separate fastening member such as a stud or insert.
