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.

Liquid crystal display device

The present invention realizes an image display of high quality by eliminating a defective display which is attributed to a stepped portion of a light shielding film which is generated in a boundary region by exposure of two or more times using an exposure mask having a size smaller than a size of a display region. Assuming a width of a scanning line GL as W, a width of a common line CL as W, an interval between the scanning line GL and the common line CL as W, and a width of a light shielding film BMas W, the relationship W&#x3c;W+W+Wis established. Further, both end peripheries of the light shielding film BMare positioned between an end periphery of the scanning line GL at a side opposite to the common line CL and an end periphery of the common line CL at a side opposite to the scanning line GL.
