The light reflective film has improved adhesive property between a light reflective layer and a hard coat layer. The light reflective film has a high refractive index layer, a low refractive index layer, a resin adhesive layer, and a hard coat layer laminated on a substrate, in this order. The hard coat layer has an active energy ray-curable resin. The resin adhesive layer has at least one resin selected from polyvinyl acetal resins, acrylic resins, and urethane resins.
