Abstract: The present invention provides a mounting structure of a liquid crystal display device, in which a first side board (213) of a backplane (21) includes an outward-raised first connection section (215) formed thereon so that the first side board (213) forms an insertion space with respect to the first connection section (215). A second side board (83) of the front bezel (8) includes an inward-recessed second connection section (85) formed thereon to correspond to the first connection section (15) so that the second side board (83) forms a channel (87) with respect to the second connection section (85). The second connection section (85) is inserted into the insertion space and is positioned against the first connection section (215). The first connection section (215) is received in the channel (87). The first connection section (215) includes a through hole (216) formed therein. The second connection section (85) includes a threaded hole (851) formed therein to correspond to the through hole (216).
