Abstract: An optical member capable of improving a vision recognition rate of a mark used for alignment such as bonding alignment, and a display apparatus including the same are discussed. The optical member can include a first layer having a pattern portion, and a second layer covering the pattern portion. At least one of the first layer or the second layer has a refractive index that is varied depending on different wavelength areas, where the wavelength areas include a visible ray area and an infrared area having a wavelength longer than that of the visible ray area. A difference in a refractive index between the first layer and the second layer is greater in the visible ray area than the infrared area.

Abstract: An optical member capable of improving a vision recognition rate of a mark used for alignment such as bonding alignment, and a display apparatus comprising the same are provided. The optical member comprises a first layer including a pattern portion having a plurality of concave portions and a plurality of convex portions between the plurality of concave portions, and a second layer covering the pattern portion. The second layer includes a central area and an outer area, and a refractive index of the second layer in the central area is different from that of the second layer in the outer area.

Abstract: An optical member capable of reducing reflectance of external light and a display apparatus comprising the same are provided. The optical member comprises a first layer including a pattern portion having a plurality of concave portions and a plurality of convex portions between the plurality of concave portions, and a second layer covering the pattern portion. The first layer and the second layer have their respective refractive indexes different from each other, and a first phase of light passing through the plurality of convex portions is different from a second phase of light passing through the plurality of concave portions.
