Abstract:
In order to prevent irreversible deformation of column-shaped spacers which retain the gap between a pair of substrates between which the liquid crystal layer of a liquid crystal display device is interposed, spacers which assist in preventing such irreversible deformation are newly provided. According to the invention, two or more kinds of spacers which differ in height from a reference surface are disposed on one of the pair of substrates. In addition, a step pattern with which the spacers are to come into contact is formed in advance on the other of the pair of substrates so that the heights of the spacers can be made different.
