Abstract

Adhesive spacer particles were fabricated to ensure the uniform cell gap between the plastic substrates for application in flexible liquid crystal display (LCD). Surface modification of rigid silica particles was performed to render adhesive polymer layer on the surface of the silica particles while maintaining the rigid properties. Methyl methacrylate (MMA) and styrene were graft-polymerized onto silica surface by UV irradiation and characterization experiments confirmed the formation of covalent bond between polymer and silica particle. FE-SEM image analysis indicated substantial increase in mean diameter of the particles after UV-induced grafting of the monomers. T-peel test value of 2.7N/cm for PMMA film/Polyimide-PES substrate system also confirmed the applicability of these composites in flexible LCD.
