摘要： Provided are a resin molded body and applications thereof. The resin molded body includes a resin layer containing a resin and a compound represented by Formula (1), and on at least one surface of the resin layer, a protective layer that contains at least one substance selected from the group consisting of urethane resin, acrylic resin, and polysiloxane. In Formula (1), Het 1 represents a divalent 5-membered or 6-membered aromatic heterocyclic residue. X a , X b , X c , and X d each independently represent a hetero atom, and Y a , Y b , Y c , Y d , Y e , and Y f each independently represent a hetero atom or a carbon atom. A ring bonded to Het 1 may have a double bond at any position.
