Development of pigment‐dispersed‐type color filters for LCDs

Abstract

Abstract— Our newly developed color filter for liquid‐crystal displays is made with highly photo‐sensitive pigment‐dispersed photopolymer to satisfy the increasing demand for better specifications. This color filter has high photosensitivity, good color characteristics such as high color contrast and color purity, and strong durability against heat, light, and chemicals. The copolymer composition of the improved pigment‐dispersed photopolymer and the characteristics of its color filter are mainly discussed from the standpoint of stability and color.
