Abstract: PURPOSE:To disperse spacer materials which hold the gap between substrates nearly uniform by the electric resiliency of each spacer material by holding the spacer materials electrically in the same polarity. CONSTITUTION:The spacer materials 5 are charged electrostatically to the same polarity to repulse one another individually, which is utilized to disperse the materials while they have electrically the same polarity. In this case, a substrate 1 is given the opposite polarity to facilitate the sticking of the spacer materials to the substrate, and both effects of scattering and dispersing operations are obtained. Further, the substrate is charged to attract and stick only spacer materials which are charged to the opposite polarity among the charged spacer materials, thus scattering and dispersing spacers in single-time charging operation. In this case, the polarity of charging of every substrate is made opposite to attract spacer materials which are charged alternately, so successive operations are possible.
