ABSTRACT:
It is an object of the present invention to provide a spacer for a liquid crystal display and a method of producing a spacer for a liquid crystal display, which improve light leakage around a spacer for a liquid crystal display in cutting off light of a liquid crystal display and in vibrating a liquid crystal display and in addition have a good dry spraying property.The present invention relates to a spacer for a liquid crystal display, which comprises a base particle and a polymer coating the surface of said base particle, a contact angle A1of water on the spacer, measured at 25° C. when said spacer is annealed at a temperature of an annealing temperature T1or higher in fabricating a liquid crystal display for 1 hour or more and then cooled, and a contact angle B of water on the spacer, measured at 25° C. without annealing the spacer, satisfying the relationship of the following equation (1):in-line-formulae description="In-line Formulae" end="lead"?A1−B≧1°.  (1)in-line-formulae description="In-line Formulae" end="tail"?
