Beschreibung
Zusammenfassung:	An optical member includes: a substrate; and a dot that is in contact with a surface of the substrate, in which the dot is formed of a liquid crystal material having a cholesteric structure, the substrate includes a liquid crystal layer that is formed on the surface in contact with the dot, and the liquid crystal layer is a layer in which orientation of a liquid crystal compound is immobilized. The optical member includes a dot in a shape having a large maximum height with respect to a diameter, the dot being formed of a liquid crystal material having a cholesteric structure in which orientation disorder is reduced. As a result, the detection sensitivity of the dot pattern in various directions including an oblique direction is high. By using the optical member according to the present invention, an image display device having a high data input sensitivity can be provided.
