Abstract
An electro-optical device and a method for manufacturing the electro-optical device that requires no cleaning of an electro-optical material cell, and thereby results in a high production yield. The present invention includes forming an uncured sealing member having no injection port in a loop configuration in peripheral portions of respective substrate formation regions of a counter substrate base material. Further, applying a liquid crystal (an electro-optical material) in the area surrounded by the uncured sealing member in each substrate formation region to form a liquid crystal layer (an electro-optical material layer). The counter substrate base material and the substrate base material are then bonded together with the uncured sealing member interposed therebetween, thereby forming a liquid crystal cell base material (an electro-optical cell base material). The uncured sealing member is then cured, thereby forming a sealing member. The liquid crystal cell base material is diced along the outlines of the substrate formation region and the substrate formation region.
