Abstract

The present invention provides a method for manufacturing a liquid crystal display device capable of reducing thermal damage to a polarizing plate during thermo-compression bonding, thereby sufficiently preventing the occurrence of defects due to the deformation of the polarizing plate. The method for manufacturing a liquid crystal display device according to the present invention is for thermo-compression bonding a terminal portion of a liquid crystal panel and an external circuit using a pressure bonding device configured of a stage, a heat source, and a buffer member. The manufacturing method includes placing the liquid crystal panel on the stage, and thermo-compression bonding the terminal portion of the liquid crystal panel and the external circuit by heat from the heat source via the buffer member interposed between the heat source and the external circuit. The pressure bonding device has a heat shield member that shields heat from the heat source to the polarizing plate, and/or a heat dissipation portion that dissipates heat from the heat source. In the thermo-compression bonding, the heat shield member and/or the heat dissipation portion overlap with at least a part of the polarizing plate bonded to the liquid crystal panel when planarly viewing the principal surface of the panel.
