Claim Text:
1. A method of manufacturing an image display device where an image display member and a light-transmitting cover member with a light-shielding layer formed on a peripheral portion thereof are stacked via a light-transmitting cured resin layer formed from a liquid photo-curable resin composition such that a light-shielding layer forming surface of the light-transmitting cover member is disposed on a side of the image display member, the method comprising the following steps of (A) to (D): <Step (A)> a step of applying the liquid photo-curable resin composition to the light-shielding layer forming surface of the light-transmitting cover member or a surface of the image display member to a thickness greater than that of the light-shielding layer so as to cancel a step formed between the light-shielding layer and the light-shielding layer forming surface of the light-transmitting cover member, wherein the liquid photo-curable resin composition comprises a radical photopolymerization initiator; <Step (B)> a step of pre-curing the applied photo-curable resin composition with irradiation of ultraviolet rays so as to form a pre-cured resin layer; <Step (C)> a step of bonding the light-transmitting cover member to the image display member such that the light-shielding layer and the pre-cured resin layer are located between the light-transmitting cover member and the image display member; and <Step (D)> a step of subjecting the pre-cured resin layer held between the image display member and the light-transmitting cover member to the irradiation of ultraviolet rays to completely cure the resin layer to thereby stack the image display member and the light-transmitting cover member via the light-transmitting cured resin layer to obtain the image display device, wherein the pre-curing in the step (B) is conducted so as to obtain a cure shrinkage ratio of less than 3% in the step (D) when a total value of cure shrinkage ratios of the liquid photo-curable resin composition based on the pre-curing in the step (B) and the complete curing in the step (D) is greater than 5%, and after the resin layer is completely cured, the completely cured resin layer completely covers a side of the shielding layer that is opposite to a side of the shielding layer that contacts the light-transmitting cover member, and a side of the completely cured resin layer that is opposite to the side of the completely cured resin layer that completely covers the shielding layer forms a substantially flat surface.
