METHOD OF MANUFACTURING IMAGE DISPLAY DEVICE

摘要

An image display device is manufactured by: applying a liquid photo-curable resin composition having a total value of cure shrinkage ratios based on pre-curing and complete curing of 3% or more to a surface of the light-transmitting cover member or a surface of the image display member with a thickness greater than that of the light-shielding layer to cancel the step between the light-shielding layer and the light-shielding layer forming surface of the light-transmitting cover member; pre-curing the photo-curable resin composition with the irradiation of ultraviolet rays to form a pre-cured resin layer; bonding the light-transmitting cover member to the image display member such that the pre-cured resin layer is placed inside; and subjecting the pre-cured resin layer to the irradiation of ultraviolet rays to achieve the complete curing thereof. The pre-curing is conducted to obtain a cure shrinkage ratio less than 3% in the complete curing thereof.

主权项

1. A method of manufacturing an image display device, wherein 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 steps (A) to (D):
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; pre-curing the applied photo-curable resin composition with irradiation of ultraviolet rays so as to form a pre-cured resin layer having a viscosity of 20 Pa·s or more; bonding the light-transmitting cover member to the image display member such that the light-shielding layer and the pre-cured resin layer are placed inside; and 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 liquid photo-curable resin composition comprises as main components an acrylate-based oligomer, an acrylate-based monomer, and a photopolymerization initiator.
