Method for manufacturing electrophoretic display

電気泳動ディスプレイの製造方法

Abstract

PROBLEM TO BE SOLVED: To provide a method for manufacturing an electrophoretic display to which a photopolymerizable material is applied. SOLUTION: Electrophoretic display is attained by wrapping colored and charged particles with the photopolymerizable material. In the method for manufacturing the electrophoretic display, an assist substrate provided with a buffer layer is coated with a first layer of photopolymerizable material and a photopolymerization step is performed and the first layer of photopolymerizabale material after polymerization then undergoes steps required for the electrophoretic display such as conductive layer electrode fabricating. A second layer of photopolymerizable material mixture is applied to a substrate provided with a plurality of electrode patterns and the like, the assist substrate is aligned with the substrate and the first and the second layers of photopolymerizable material are positioned between the assist substrate and the substrate, the assist substrate and the substrate are bonded to each other in a mask exposure polymerization step and the phases of a charged particle solution and the polymerized material are separated, and finally the assist substrate is removed to complete the manufacture of the electrophoretic display of a single substrate.
