Abstract
To prevent inconsistency in images and support columns from collapsing when pressure is applied from outside in the case where liquid crystal is sealed in under negative pressure in order to prevent impact bubbles from being created in the liquid crystal display device in accordance with a liquid crystal dropping and sealing method. The distance between a TFT substrateand a facing substrateis set using first support columns, while second support columnsare located within contact holesand do not make contact with the TFT substrate. When pressure is applied from outside, the second support columnsmake contact with the side wall or the like of the contact holescreated in the TFT substrate, so that the repulsive force of the second support columnsprevents the distance between the TFT substrateand the facing substratefrom becoming too small. As a result, inconsistency in images can be prevented, and the first support columnscan be prevented from collapsing when pressure is applied from outside.
