[Prior art] 'The basic structure of the night crystal display element is on the surface of the substrate of the liquid crystal display element.' A switching element or a control element that controls the alignment of liquid crystal molecules is formed by applying a voltage. The two liquid crystal display element substrates of the alignment film of (Pretilt angle) are opposed to each other through the alignment film, the switch element or the electrode, and are kept at a distance in the scattered spacers and fixed by the sealing material. Then, a liquid crystal layer is provided on a portion surrounded by the sealing material and the two liquid crystal display element substrates, and a polarizing plate is provided outside each liquid crystal display element. In the structure of such a liquid crystal display device, the alignment film is composed of an organic polymer film such as a polimide resin, and a polyimide (Polyamide) -based synthetic fiber is used for the alignment film. The surface is subjected to alignment treatment such as rubbing, and the liquid crystal molecules are given a predetermined alignment. · As shown in Fig. 1, the friction device used for such an alignment process is formed by rotating a friction roller 2 with a friction cloth 22 adhered to a cylindrical metal roller 2 丨 in the direction of an arrow, and forming friction in the same direction at the same time. The surface of the alignment film 13 of the liquid crystal display element substrate 1 restricts the molecular alignment direction of the liquid crystal layer provided between the two liquid crystal display element substrates to the rubbing direction (for example, refer to Japanese Patent Document 1). 5 314754 200416459 This patent document l

The purpose of the full display of LCD display elements @. However, in recent years, there has been a trend to increase the size of extraordinary pieces, and products in both vertical and horizontal sizes have been commercialized. Therefore, it is also necessary to use the friction device used in the orientation processing step ~ if you use "八." At this time, as shown in Fig. 2, when the thickness increases and the thickness increases, the central part along the length direction of the curved Yang roll with the length of the cylinder will bend due to its own weight. Under the invitation of the sentence “Feng Yuan's weight in the liquid crystal display”, he was rubbed, Du Guo ;: The alignment film 33 of 2: 2 lost the uniformity in unevenness, and there was a blunder, etc .: The full display of the display element was connected to the friction cloth. The friction roller pair belongs to the following: When the friction roller is rotated with a general adhesive, when the friction cloth is subjected to the alignment treatment, when the electricity is applied, the floating on the alignment film is caused by the friction of "^ The static is like the existence of a pinhole part. The knife prevents the existence of liquid crystal, so that the present invention is developed in view of the above-mentioned alignment process using the roller to perform the alignment process. The developer was rubbed against the liquid crystal display under the pressure of liquid uniformity. Use friction rollers and ^ 'Large size of the crystal display element in the process of the liquid crystal display element can also be the alignment film on the entire surface of the element substrate, and 3) 4754 6 200416459 shows the alignment fluff of the element substrate. Because the display level is higher than when the alignment treatment is performed, the liquid crystal can be electrostatically generated during friction and absorb dust or high liquid crystal display elements. (Means for Solving the Problem)-The invention described in the poor patent application is to be arranged in Liquid crystal display element substrate grabbing: One orientation film formed by the covering method of the item and the electrode: and at least using carbon fiber strength: =. In addition, the friction roller has a cylindrical shape, and the application of the present invention The scope of the patent, the scope of the second patent, and the scope of the invention are ^ τ, the track friction, μ, λ, and the components of the reinforced plastic outer cylinder. Electroplated stainless steel. In the 3rd patent application scope of the invention, the 2nd, 10th, and rth members of the invention are contained in an emperor, and the friction roller is described in the aforementioned non-zirconium. You have Overplated surface The conductive friction material is used to connect the viscous friction cloth with a conductive material. Furthermore, the application name of the present invention is the invention described in item 4 of the scope of patent application, and the orientation treatment θ θ _ 、 Any of the friction display devices that are subject to any of the disciplines. [Embodiment] The best description of the present invention will be described in detail. In addition, the implementation is described below, so the technical scope is not limited to the following. First and the fourth embodiment (same-partially conferring the same aspect are the best and best limitations of the present invention, but the present invention is not limited to these aspects.
