An adhesive sheet includes a substrate and an energy-ray curable adhesive layer formed on the substrate. The energy-ray curable adhesive layer includes an energy-ray curable acrylic copolymer and an energy-ray curable urethane acrylate. The energy-ray curable acrylic copolymer is formed by copolymerizing dialkyl(meth)acrylamide and includes a side chain with an unsaturated group. The energy-ray curable urethane acrylate includes an isocyanate block and a (meth)acryloyl group. The isocyanate block includes at least one of an isophorone diisocyanate, a trimethyl-hexamethyene diisocyanate, and a tetramethyl-xylene diisocyanate.
