ABSTRACT:
A uniform gap thickness is maintained in a liquid crystal cell by introducing, into a sealing portion of the cell, between two substrates, glass balls having a diameter substantially equal to the desired gap space between the substrates and columnar glass fibers. The combination of the balls and the fibers enables the quality of the image produced by the liquid crystal cell to be improved. In particular, the image quality is made more uniform in color tome and contrast.
