Abstract
Organic-inorganic composite particles which include a (meth)acrylic resin framework and a polysiloxane framework having in its molecule an organosilicon containing a silicon atom directly and chemically combined with at least one carbon atom of the (meth)acrylic resin framework, and also contain 25 wt % or more of SiO.sub.2 which constitutes the polysiloxane framework and have a mean particle diameter of .gtoreq.0.5 .mu.m. The particles have the mechanical resilience necessary to maintain a constant gap distance between a pair of members to be arranged with the correct gap distance between them, and the hardness and fracture strength necessary to maintain the gap constant with smaller numbers; and also do not readily cause physical damage to the members. The composite particles can be employed as spacers 8 for a liquid crystal display as they stand or with an adhesive layer formed on the surface. The composite particles can also have a conductive layer formed on the surface, and be employed as conductive particles.
