To provide a method for manufacturing an image display device, in which when a light/moisture dual curing-type curable composition is filled into the space between an image display panel module and a transparent cover board, or the like, even a portion not exposed to light is not left uncured, and further, insufficient curing at a central portion of the inside of the panel can be suppressed.

A method for manufacturing an image display device is characterized in that a curable composition including a compound (A) having at least one hydrolyzable silyl group in one molecule on average, a compound (B) having at least one polymerizable carbon-carbon double bond in one molecule on average, a photopolymerization initiator (C), a curing catalyst (D), and a photo-acid-generating agent (E) is filled into at least one space between an image display panel module of a flat panel display and a transparent cover board, between an electrode substrate for a touch panel and the transparent cover board, and between the image display panel module and the electrode substrate for the touch panel, and the curable composition is cured by UV irradiation.
