Abstract: A display apparatus includes a display element disposed over a substrate, a light blocking layer disposed over the display element, the light blocking layer including an opening corresponding to the display element, a first high-refraction layer disposed in the opening of the light blocking layer, a first low-refraction layer overlapping the light blocking layer and the first high-refraction layer in a plan view, the first low-refraction layer having a refractive index that is lower than a refractive index of the first high-refraction layer, and scattering particles disposed over the display element.
