(1) used for joining an optical substrate and an optical substrate having a light- (A), a photopolymerizable compound (B) and a photopolymerization initiator (C) represented by the following general formula (1), a cured product obtained by irradiating the adhesive with ultraviolet rays, Such as a touch panel. By using the ultraviolet curable adhesive of the present invention, even when a light shielding portion is formed on an optical substrate such as a transparent shielding plate, no damage is given to the liquid crystal display device or the like, and light shielding by the presence of the light shielding portion by irradiation of ultraviolet light from one direction The adhesive located in the light shielding region can be sufficiently cured. |
