Utilization of Monodisperse Polymer Particles as Spacer Particles for Liquid Crystal Display

Utilization of monodisperse polymer particles, which were prepared by “Accelerated Molecular Diffusion”seeding polymerization, as spacer particles was investigated. Compressive behavior was measured with a micro-compressive instrument on each particle. The 10% compressive modulus (E10%) was defined as the modulus obtained when the particle was deformed to an extent of 10% of its diameter. The cell thickness of liquid crystal display (LCD) panel was simulated on the basis of particle size distribution, elastic modulus, and the number of spacer particles. As a result, even when spacer particles in the LCD panel fluctuated, spacer particles having narrow particle size distribution keep the minute cell thickness constant and monodisperse spacer particles having a high compressive modulus keep the constancy of cell thickness. These simulation results were in good agreement with the experimental results on LCD panel assembly.
