Disclosed is an LCD module that has a cushion member, or a plurality of buffer structures, which prevents mechanical deformation of the LCD panel, and the light leakage that results from the mechanical deformation. The plurality of cushion members are bonded to only a single inside edge of the panel guide and evenly distanced such that they provide a cushion to the LCD panel to reduce a concentrated weight generated by pressing due to the weight of the LCD panel. The cushion member, or the plurality of buffer structures, prevents mechanical deformation by distributing the weight of the LCD panel. The LCD module comprises an LCD panel, a backlight assembly, and a guide panel having the cushion member or buffer structures.
