Abstract
Provided are an optical laminate where the occurrence of crosstalk can be suppressed and the occurrence of multiple images can be suppressed, a light guide element, and an image display apparatus. The optical laminate includes: a first cholesteric liquid crystal layer and a second cholesteric liquid crystal layer that are obtained by immobilizing a cholesteric liquid crystalline phase and have a liquid crystal alignment pattern in which a direction of an optical axis derived from a liquid crystal compound changes while continuously rotating in at least one in-plane direction, in the first and second cholesteric liquid crystal layers, turning directions of circularly polarized light to be reflected are opposite to each other, helical pitches Pand Pof the first and second cholesteric liquid crystal layers satisfy P<P, rotation directions of the direction of the optical axis derived from the liquid crystal compound that continuously rotates in one in-plane direction in the liquid crystal alignment pattern are opposite to each other, and lengths Λand Λof the single periods of the first and second cholesteric liquid crystal layers satisfy Λ<Λ.
