    • 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 substrate 10 and a facing substrate 20 is set using first support columns 30, while second support columns 40 are located within contact holes 50 and do not make contact with the TFT substrate 10. When pressure is applied from outside, the second support columns 40 make contact with the side wall or the like of the contact holes 50 created in the TFT substrate 10, so that the repulsive force of the second support columns 40 prevents the distance between the TFT substrate 10 and the facing substrate 20 from becoming too small. As a result, inconsistency in images can be prevented, and the first support columns 30 can be prevented from collapsing when pressure is applied from outside.
