The mounting structure is constructed with a reinforcing member installed on a chassis base of the display module, a boss including a threaded length having an outer portion on which a screw surface is formed and being coupled to the reinforcing member, and a connecting portion extending from the threaded length in a direction away from the reinforcing member and having an end portion in which a coupling hole is formed, and a supporting nut screwed into the threaded length to press the boss toward the reinforcing member.
