    摘要: A spherical spacer is provided for defining a gap dimension between substrates of a liquid crystal display. The K-value (hardness of a sphere) of the spherical spacer is defined as: ##EQU1## (wherein F and S represent a load value (kgf) and a compression displacement (mm) at 10% compression deformation of said fine sphere, respectively, and R represents a radius (mm) of said fine sphere) which is in the range of 250 kgf/mm.sup.2 to 700 kgf/mm.sup.2 at 20.degree. C.; and a recovery factor after the compression deformation which is in the range of 30% to 80% at 20.degree. C. A spherical spacer matching the newly found limitations and defining the gap between a pair of substrates into which liquid crystal is filled reduces the damage to an alignment coat when compared with spacers being too hard, and reduces quality deterioration of the image when compared with spacers being too soft.
