Abstract:
A method for manufacturing an electro-optical device including a sealing member that is formed to bond a pair of opposing substrates that encapsulate an electro-optical layer therebetween, and a pair of substrate base materials, each of which includes a plurality of substrate formation regions on which the respective substrates are formed, the method of comprising:forming an uncured sealing member by applying an uncured adhesive in a loop configuration in a peripheral portion of each substrate formation region of one of the pair of substrate base materials; fabricating an electro-optical layer by applying an electro-optical material in an internal area surrounded by the uncured sealing member in each substrate formation region of the substrate base material; assembling an electro-optical cell base material by bonding the one substrate base material to the other substrate base material with the uncured sealing member interposed therebetween; curing the uncured sealing member of the electro-optical cell base material; and dicing the electro-optical cell base material along each substrate formation region; the step of fabricating the electro-optical layer including applying the electro-optical material on the one substrate in the internal area surrounded by the uncured sealing member using an ink-jet nozzle that discharges droplets of the electro-optical material; wherein when the electro-optical material is applied, the viscosity of the electro-optical material is within a range from 1 to 50 mPaxs; and the step of curing the uncured sealing member includes curing the uncured sealing member by irradiating, with ultraviolet light, only the area of the electro-optical cell base material, having the uncured sealing member formed therewithin.
