    Abstract: A display apparatus includes a display panel configured to display an image, a light guide member below the display panel, a light source adjacent to at least one surface of the light guide member, and an optical member between the light guide member and the display panel. The optical member includes a wavelength conversion layer configured to convert a wavelength band of incident light. A low refractive index layer between the wavelength conversion layer and the light guide member and including a plurality of pores, and an inorganic layer between the low refractive index layer and the wavelength conversion layer. A volume ratio occupied by the pores within the low refractive index layer increases as being closer to the light guide member.

    Abstract: An optical filter including a plurality of color areas and a surrounding area includes a substrate, a first optical layer on the substrate and including a first to third color filter respectively in a first to third color area, a second optical layer including a first color conversion portion, a second color conversion portion and a light transmission portion respectively overlapping the first color filter, the second color filter and the third color filter, and a light blocking layer, where the light blocking layer includes a body portion in the surrounding area including a light blocking material, and the body portion surrounds both a first and a second opening. The first and second color area are adjacent to each other and an area between the first and the second color area correspond to the first opening, and the third color area corresponds to the second opening.
