The present invention relates to a holographic optical element and a method for manufacturing same and, specifically, to: a holographic optical element using a retardation layer to prevent unwanted interference patterns from being formed in the process of recording an interference pattern on a photopolymer resin layer; and a method for manufacturing same. La présente invention concerne un élément optique holographique et son procédé de fabrication et, spécifiquement : un élément optique holographique utilisant une couche de retard pour empêcher des motifs d'interférence indésirables d'être formés dans le processus d'enregistrement d'un motif d'interférence sur une couche de résine photopolymère; et un procédé de fabrication de celui-ci.
