Fine sphere, a spherical spacer for a liquid crystal display element and a liquid crystal element using the same

摘要

A conductive fine sphere with a K-value and a recovery factor in a predetermined range is provided. Suppose a load value (kgf) is F, a compression displacement (mm) is S, and a radius (mm) is R at 10% compression deformation of this spacer, a K-value defined as the following equation is in the range of 250 kgf/mm2 to 700 kgf/mm2 at 20 DEG C., and a recovery factor after the compression deformation is in the range of 30% to 80% at 20 DEG C., and
