Abstract
To suppress occurrence of low temperature bubbles while securing pressure resistance to external forces applied to substrates of a liquid crystal display device, a plurality of spacers disposed between the substrates are divided into a plurality of spacer groups, one unit of which is configured with spacersallocated in close proximity to each other; and the spacer groupsare disposed with a density that the low temperature bubbles do not occur. Hence, the strength of the substrates increases, and in a regionwhere no spacers exist, a large deformation of the substrates by shrinkage is allowed, and a liquid crystal layeris sufficiently enough shrunk even under a low temperature environment to prevent the low temperature bubbles from occurring.
