Definitions

  • the present invention relates to a rubbing cloth used in a rubbing process for controlling the alignment of liquid crystal molecules in a liquid crystal panel manufacturing process.
  • a liquid crystal display element used in a transmissive liquid crystal display device includes a TFT substrate on which a driving element (TFT) made of a thin film transistor is formed, a color filter substrate on which a color filter is formed (hereinafter abbreviated as a CF substrate), Are arranged so as to face each other with a small interval, and a liquid crystal is sealed in the gap.
  • a patterned ITO electrode is disposed as a pixel electrode on the surface of the TFT substrate, and an alignment film is disposed so as to cover the surface of the ITO electrode.
  • an ITO film is disposed as a common electrode on the surface of the CF substrate, and an alignment film is disposed on the surface of the ITO film.
  • the TFT substrate and the CF substrate are disposed to face each other so that the alignment films face each other. Both alignment films on both substrates are in contact with the liquid crystal to be sealed.
  • the alignment film of the TFT substrate and the CF substrate is subjected to an alignment process in order to align liquid crystal molecules.
  • a rubbing method in which the surface of the alignment film is rubbed with a rubbing cloth is mainly used.
  • the rubbing cloth is used by being attached to the outer peripheral surface of an aluminum or stainless steel roller.
  • the rubbing cloth affixed to the outer peripheral surface is brought into contact with the alignment film surface while rotating the roller, and the surface is rubbed.
  • a velvet made of a base cloth and a pile of raised fibers is generally used.
  • the pile density of the velvet for the rubbing cloth is adjusted by changing the thickness of the pile or the thickness of the yarn used for the base cloth. Furthermore, the pile length is adjusted by the cutting position from the base fabric.
  • a fiber material used for the pile portion one using a long fiber (filament) such as rayon or nylon and one using a short fiber such as cotton are known.
  • the rubbing cloth in which the pile portion is formed of rayon has a problem that the abrasion resistance of rayon is insufficient. For this reason, in the rubbing cloth made of rayon, the pile is worn during the rubbing process, and wear powder is likely to be generated. When this wear powder adheres to the alignment film surface, the distance (liquid crystal cell gap) between the two glass substrate surfaces facing each other of the liquid crystal display element becomes non-uniform, causing defects such as display unevenness. In addition, the abrasion powder is easily caught in the rubbing cloth. When the alignment film is rubbed in a state where the abrasion powder is wound on the rubbing cloth, the alignment film surface is scratched. This scratch causes the liquid crystal display element to have a part that shines white. Furthermore, since the worn rubbing cloth lacks uniformity, if it is used while worn, the rubbing treatment becomes non-uniform, which causes display unevenness of the liquid crystal display element. For this reason, it is necessary to replace the rayon rubbing cloth as soon as possible.
  • Rubbing cloth made of cotton is slightly improved compared to rayon in the abrasion resistance of the pile. This is because the basic skeleton of both cotton and rayon is cellulose, but cotton has a higher molecular weight and higher material strength than rayon.
  • the pile yarn constituting the pile portion is a spun yarn obtained by spinning the staple fiber.
  • the thickness of each pile is thicker than that of synthetic fibers such as nylon and pile fibers whose pile yarns are made of filaments, and regenerated fibers such as rayon.
  • synthetic fibers such as nylon and pile fibers whose pile yarns are made of filaments, and regenerated fibers such as rayon.
  • the short fiber of cotton tends to fall on the substrate during rubbing.
  • the rubbing cloth made of cotton has slightly improved wear resistance as compared with the rubbing cloth made of rayon, but has a problem that the pile yarn becomes thick and the uniformity of the pile is low.
  • Rubbing cloth made of polyester or nylon is generally more resistant to abrasion than rayon or cotton rubbing cloth, so that generation of abrasion powder is suppressed more than rayon or cotton rubbing cloth.
  • the rubbing cloth made of nylon has a problem that the rubbing cloth is charged to a high voltage due to static electricity generated during rubbing. Specifically, since a nylon rubbing cloth has a high voltage when rubbing, there is a risk of damaging the TFT elements and wiring when this is short-circuited with the substrate.
  • JP7-270798A describes that the wear resistance of a pile of rubbing cloth can be improved by using an aramid fiber.
  • aramid fibers have a high degree of crystallinity and excellent tensile strength, but they are weak to the shearing force that the pile receives during rubbing, and the fibers may tear in the longitudinal direction. There is a problem that a large amount of fibrils fall off due to the fibers tearing in the longitudinal direction, which becomes a foreign matter on the alignment film.
  • JP6-194462A describes the use of fibrous proteins such as collagen and silk fibroin for rubbing cloth.
  • fibrous proteins have the disadvantage of low heat resistance.
  • the thermal decomposition temperature of rayon is 260 to 300 ° C.
  • silk is thermally decomposed from 235 ° C.
  • wool is decomposed from 130 ° C. For this reason, it is easily denatured by frictional heat generated during rubbing and cannot be used as a rubbing cloth.

Further, by making the difference between the maximum value and the minimum value of the compressive stress 200 gf / cm 2 or less, a more stable rubbing effect can be obtained.
