Title:
SPACER FOR LIQUID CRYSTAL DISPLAY AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2004/051352
Kind Code:
A1
Abstract:
A spacer for liquid crystal display that realizes improvement to light slipping around the spacer for liquid crystal display at light cutoff and vibration of the liquid crystal display and excels in dry spreadability; and a process for producing the spacer for liquid crystal display. In particular, a spacer for liquid crystal display comprising base particles whose surface is coated with a polymer, which spacer satisfies the relationship of the formula: A1 - B ≥ 1&ring (1) wherein A1 represents a water contact angle measured at 25&ring C after a procedure comprising annealing for 1 hr or more at a temperature not lower than the anneal temperature (T1) during liquid crystal display production and cooling, and B represents a water contact angle measured at 25&ring C without performing the above annealing operation.
