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: A display apparatus and a coherence prevention member are discussed. The display apparatus in one example includes a display panel configured to display an image, and a coherence prevention layer on the display panel. The coherence prevention layer includes a refractive index particle layer and a filling layer on the refractive index particle layer. The refractive index particle layer includes a light-transmissive matrix and refractive index particles dispersed in the light-transmissive matrix. Further, the filling layer and the refractive index particles have different refractive indices.
