Diversity of changes in accordance with the observation conditions of an image displayed by an optical element including a solidified liquid crystal material is improved. An optical element (10) includes a laminated body and a reflection layer (12) facing the laminated body. The laminated body includes a light transmitting recessed section forming layer (13) whose one main surface includes one or more recessed section forming regions. In the recessed section forming regions, a plurality of grooves having the same lengthwise direction by being adjacent to each other in a direction intersecting with the lengthwise direction are formed, respectively. The laminated body also includes a liquid crystal layer (15) which is supported by the main surface and is composed of the solidified liquid crystal material.
L'invention propose plusieurs améliorations relatives aux conditions d'observation d'une image affichée par un élément optique comprenant une matière à cristaux liquides solidifiée. Un élément optique (10) comporte un corps laminé et une couche de réflexion (12) tournée vers le corps laminé. Le corps laminé comporte une couche (13) de formation de sections renfoncées transmettant de la lumière, dont une surface principale comporte une ou plusieurs zones de formation de sections renfoncées. Dans les zones de formation de sections renfoncées, une pluralité de rainures est formée, toutes dans le sens longitudinal et adjacentes les unes aux autres, perpendiculairement à la direction longitudinale respectivement. Le corps laminé comprend également une couche (15) de cristaux liquides supportée par la surface principale et composée de matière à cristaux liquides solidifiée.
