    • An organic-inorganic composite particle, which comprises a particle body having an elastic modulus of 350-3000 kg/mm 2 in 10% compression, a residual displacement of 0-5% after 10% deformation, a mean particle diameter of 0.5-50 µm and a coefficient of variation of 20% or less in particle diameter, said particle body including:

      an organic group; and
      a polysiloxane framework which has in its molecule an organosilicon containing a silicon atom directly and chemically combined with at least one carbon atom of said organic group. 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 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.
    • 一种有机 - 无机复合颗粒,其包含在10%压缩下弹性模量为350-3000kg / mm 2的颗粒体,10%变形后的残余位移为0-5%,平均粒径为0.5 -50μm,粒径变化系数为20%以下,所述粒子体包含:有机基团; 以及聚硅氧烷骨架,其分子中含有硅原子的有机硅与所述有机基团的至少一个碳原子直接化学结合。 颗粒具有必要的机械弹性,以保持要布置的一对构件之间的间隙距离与它们之间的正确间隙距离保持恒定的间隙距离,以及维持间隙恒定的硬度和断裂强度较小; 也不会对成员造成身体伤害。 复合颗粒可以用作液晶显示器的间隔物,或者在表面上形成粘合剂层。 复合颗粒也可以具有在表面上形成的导电层,并且用作导电颗粒。
