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.
