Title:
光学積層体、導光素子およびＡＲ表示デバイス
Document Type and Number:
Japanese Patent JP7261810
Kind Code:
B2
Abstract:
Provided are an optical laminate in which a large diffraction angle can be obtained, a light guide element, and an AR display device. The optical laminate includes, in the following order: a first optically-anisotropic layer that is formed of a composition including a liquid crystal compound and has a liquid crystal alignment pattern in which a direction of an optical axis derived from the liquid crystal compound continuously rotates in at least one in-plane direction; a phase difference layer; and a patterned cholesteric liquid crystal layer that is formed of a composition including a liquid crystal compound and has a liquid crystal alignment pattern in which a direction of an optical axis derived from the liquid crystal compound continuously rotates in at least one in-plane direction, the liquid crystal compound being cholesterically aligned, in which in the first optically-anisotropic layer and the patterned cholesteric liquid crystal layer, the one in-plane directions in which the direction of the optical axis derived from the liquid crystal compound continuously rotates are the same, and rotation directions of the direction of the optical axis derived from the liquid crystal compound in the one in-plane direction are the same.
