    摘要： 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.

    摘要： A display device according to the present disclosure includes first and second substrates transmitting visible light, light emitting pixels, a first internal layer, a liquid crystal layer, a first electrode reflecting visible light, and second to fourth electrodes transmitting visible light. The light emitting pixels independently emit light. The liquid crystal layer is located between the first and second substrates. The first electrode is located between at least one of the light emitting pixels and the liquid crystal layer. The second electrode is located between the liquid crystal layer and the first substrate without overlapping the first electrode in plan view. The third electrode is located between the liquid crystal layer and the second substrate while overlapping the first electrode in plan view. The fourth electrode is located between the liquid crystal layer and the second substrate while overlapping the second electrode in plan view.

    摘要： A color conversion film for a backlight unit comprising an array of light emitting diodes includes a substantially planar base portion configured to receive light from a light source positioned below the substantially planar base portion. A plurality of three-dimensional structures are configured to extend from the substantially planar base portion in a direction away from the light source, where each of the plurality of three-dimensional structures having at least one sloped surface at an angle Θ relative to the substantially planar base portion such that each of the plurality of three-dimensional structures comprises a decreasing cross-section as light travels away from the light source.
