Abstract

PURPOSE:To enable uniform rubbing in a short time by carrying out rubbing while changing over a rough rubbing material to a dense one. CONSTITUTION:A transparent electrode substrate 3 is subjected to preliminary processing (rough rubbing) with a rough rubbing material 5 having a lower degree of flocking and to precision processing (precision rubbing) with a dense rubbing material 6 having a higher degree of flocking. This method can considerably reduce the time required to carry out uniform rubbing by a conventional repeated rubbing method using the same rubbing material.

Chemical fibers such as nylon and Tetron are often used as materials for rubbing materials, but in Figure 4, fabrics in which the chemical fibers are flocked by electro-flocking are used. ) is a rubbing material with a coarse flocking degree, and (6) is a rubbing material with a dense flocking degree. Then, a pretreatment (rough rubbing) is performed using a rubbing material (5) with a coarse flocking layer, and then a precision treatment (precision rubbing) is performed using a rubbing material (6) with a gradually dense flocking layer. This makes it possible to perform uniform rubbing within a short period of time.
