Abstract: A liquid crystal display device module has a structure for preventing wrinkles in the reflective sheet by providing a means for supporting a light guide plate. In one embodiment, the means includes a supporting member positioned between a supporting frame and a light guide plate. The thickness of the supporting member is larger than that of the reflective sheet, and thus the reflective sheet is prevented from being affected by internal and external heat. Moreover, in one embodiment the supporting frame has a step portion in a peripheral area. The step portion has a step that has a height being larger than the reflective sheet, and thus the reflective sheet is prevented from being affected by internal and external heat, too. Accordingly, wrinkles do not occur in the reflective sheet, and the quality of the LCD module is raised, and thus a liquid crystal display device having good display characteristics can be attained.
