a display module includes : a main liquid crystal panel having a plurality of pixel regions formed on a surface thereof so as to display visual information ; a barrier panel spaced a predetermined gap from the surface in the thickness direction so as to cover the surface of the main liquid crystal panel ; and a refractive portion including at least one glass substrate so as to fill the gap . the freedom of design may be increased since the display module can maintain a prescribed thickness , and the portability may be improved by increasing rigidity .
