The invention discloses a method for mounting and dismounting a large liquid crystal display panel. The method comprises: (1), a fixed base, an overturning mechanism, a horizontal pushing mechanism, and a positioning component are set; (2), the horizontal pushing mechanism overturns downwardly at an angle; (3), a large liquid crystal display panel is arranged in the positioning component at the horizontal pushing mechanism; (4), the overturning mechanism drives the horizontal pushing mechanism and the large liquid crystal display panel to overturn upwardly and thus the horizontal pushing mechanism is in a horizontal state; (5), the large liquid crystal display panel moves forwardly and horizontally to a front stop position; (6), the large liquid crystal display panel moves backwardly and horizontally to a rear stop position; and (7), the horizontal pushing mechanism and the large liquid crystal display panel overturn downwardly. A large liquid crystal display panel carrying part formed by two L-shaped aluminum strips is used for supporting the liquid crystal display panel, thereby eliminating the sucking trace of the octopus sucking disk on the panel. The horizontal pushing mechanism overturns and thus the liquid crystal display panel extends into a table top of a metallographic microscope or is pulled out of the table top of the metallographic microscope by the horizontal pushing mechanism; and the whole operation track is stable and accurate, so that the damages of the panel and the microscope can be avoided.
