A method of scattering a predetermined amount of fine particles, in particular, selectively scattering spacers between patterned transparent electrodes formed on a substrate for a liquid crystal display. According to this method, spacers are uniformly distributed on the substrate while maintaining an adequate aperture ratio. This method provides uniform cell thickness, and high-contrast and uniform display. The method comprises applying a voltage of the same polarity as the electric charge on the fine particles to a plurality of electrodes formed on the substrate, and scattering fine particles by the repulsive force acting on the particles.
L'invention porte sur un procédé de diffusion de quantités données de particules fines et en particulier de diffusion sélective d'éléments d'espacement entre des électrodes transparentes à motif, formées sur un substrat, pour créer un affichage à cristaux liquides. Ce procédé, qui permet de diffuser lesdits éléments uniformément sur le substrat tout en maintenant un taux d'ouverture idoine, donne une épaisseur de cellules uniforme, un contraste élevé et un affichage uniforme. Ledit procédé consiste à appliquer une tension de même polarité que la charge électrique des particules fines à plusieurs électrodes formées sur le substrat, puis à laisser diffuser les particules fines sous l'effet des forces de répulsion agissant sur elles.
