Disclosed is a sealing material for liquid crystals having high adhesion strength and excellent gap-forming power at bonding of panels. Also disclosed are a method for producing such a sealing material and a method for producing a liquid crystal display cell which is improved in productivity, high-speed response and reliability. The sealing material for liquid crystals is produced through a step wherein fine particles (D) having an average particle diameter of not more than 3 µm are dispersed, using a wet dispersion unit (A), in a reactive resin (C) having an epoxy group and/or a (meth)acryloyl group which resin has been dissolved in a solvent (B) and a following step wherein the solvent (B) is removed.
Il est prévu un matériau d~étanchéité pour cristaux liquides ayant une force d~adhérence élevée et un excellent pouvoir de formation d~entrefer pour coller des panneaux. Il est également prévu un procédé de fabrication d~un tel matériau d'étanchéité et un procédé de fabrication d~une cellule d'affichage à cristaux liquides, d~une productivité accrue, d~une réaction à grande vitesse et de grande fiabilité. Le matériau d'étanchéité pour cristaux liquides est produit lors d~une phase dans laquelle on disperse de fines particules (D) d~un diamètre particulaire moyen ne dépassant pas 3 µm, à l~aide d~une unité de dispersion humide (A), dans une résine réactive (C) ayant un groupe époxy et/ou un groupe (méth)acryloyle, laquelle résine a été dissoute dans un solvant (B) et une autre phase dans laquelle on retire le solvant (B).
