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.
