The present invention relates to an ultraviolet curable adhesive, a cured product obtained by irradiating the adhesive with ultraviolet rays, and an optical member such as a touch panel containing the cured product, wherein the ultraviolet curable adhesive is used for an optical substrate and a surface. The optical base material having a light-shielding portion containing a compound (A) that absorbs ultraviolet light and emits light, a photopolymerizable compound (B), and a photopolymerization initiator (C). 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 protective plate, the liquid crystal display device or the like is not damaged, and ultraviolet rays are irradiated from a single direction. The adhesive in the shading area which is shielded by the presence of the light-shielding portion is completely hardened. |
