Abstract: A display device capable of reducing reflection of external light is provided. The display device includes a substrate on which a display area and a non-display area are disposed; a light-emitting element disposed in a sub-pixel of the display area; an encapsulation layer covering the light-emitting element; a black matrix disposed on the encapsulation layer; a color filter overlapping the light-emitting element and covering an edge of the black matrix; and a low refractive index layer covering at least a portion of an upper surface of the black matrix and at least a portion of an upper surface of the color filter, wherein the low refractive index layer has a refractive index lower than a refractive index of each of the black matrix and the color filter.
