Abstract
An optical laminate includes a cholesteric liquid crystal layer and a lenticular lens which is laminated on the cholesteric liquid crystal layer, the cholesteric liquid crystal layer has a plurality of regions which are arranged in a pattern in an arrangement direction of lenses of the lenticular lens and are different from each other in terms of the reflection center wavelength for front incident light, and among the plurality of regions, a region having the shortest reflection center wavelength is disposed at a focus position of the lenticular lens for the front incident light, and among the plurality of regions, a region having a longer reflection center wavelength is disposed further away from the focus position.
