「発明が解決しようとする問題点」
しかしながら、上記の液晶表示素子の製造方法にあって
は以下に述べるような不都合がある。"Problems to be Solved by the Invention" However, the above method for manufacturing a liquid crystal display element has the following disadvantages.

分が配向不良となり、よって液晶表示素子として作動さ
せた際に表示不良として視認される。When the alignment film is rubbed with a rubbing material during the rubbing process, static electricity is generated due to friction and this discharges, resulting in partial electrostatic damage to the alignment film and the segment electrodes or common electrodes located below, resulting in holes. . When holes are generated due to such electrostatic discharge damage, alignment defects occur in the portions of the holes, which are visually recognized as display defects when operated as a liquid crystal display element.

することができる。"Effects of the Invention" As explained above, in the method for manufacturing a liquid crystal display element of the present invention, after the alignment film is formed and prior to the rubbing treatment, the alignment film is subjected to ultraviolet irradiation treatment, so that the ultraviolet rays remove the light in the atmosphere. The active oxygen generated from the air and the energy of the ultraviolet rays themselves can remove stains on the surface of the alignment film, and further modify and harden it. This makes it possible to improve the passage of the fibers of the rubbing material during the rubbing process, thereby reducing the occurrence of friction on the alignment film. It is possible to produce a liquid crystal display element that prevents electrostatic damage and has good visibility without inconveniences such as display defects.
