1. A laminated optical component, comprising:
a transparent substrate;
a transparent adhesive layer superposed on the transparent substrate, the transparent adhesive layer including both a first type of crosslinking and a second type of crosslinking of (meth)acrylic polymer, the first type of crosslinking being formed of a first reaction site selected from a first group consisting of: a hydroxyl group, a carboxyl group, and an amino group, and a second reaction site selected from a second group consisting of: an isocyanate group, an epoxy group, and a metal atom, and the second type of crosslinking being formed by addition polymerization of unsaturated double bond; and
a transparent film superposed on the transparent adhesive layer,
wherein the transparent substrate, the transparent adhesive layer, and the transparent film form a flush-ended laminate having an end surface, the end surface of the flush-ended laminate including respective cut surfaces of the transparent substrate, the transparent adhesive layer, and the transparent film that are flush with each other,
wherein a light blocking design part is partially formed on one of:
a surface of the transparent film facing a portion of the transparent substrate on which no design part is formed; and
a surface of the transparent substrate opposite to a surface facing a portion of the transparent film on which no design part is formed, and
wherein the end surface of the laminate further includes a cut surface of the light blocking design part in a flush manner.
