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 Aof water on the spacer, measured at 25° C. when said spacer is annealed at a temperature of an annealing temperature Tor 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):1−≧1°.  (1)
