Abstract

The invention discloses a friction machine for alignment fabrication of a liquid crystal cell, which comprises at least three friction rollers arranged from forward to backward, and friction cloth moving under drive of the friction rollers. The bottom of the first friction roller is higher than that of the second friction roller, a guide dip angle formed by the friction cloth arranged between the bottom of the first friction roller and the bottom of the second friction roller and a to-be-rubbed surface is an acute angle, and the bottoms of the second friction roller and the other friction roller other than the first one are leveled with one another. The invention also discloses a liquid crystal cell fabrication method using the friction machine for friction alignment, a liquid crystal cell fabricated by the method, and a liquid crystal display device using the liquid crystal cell. The invention overcomes the problems of peeling and warpage when an alignment layer on a substrate is subjected to friction alignment.
