Abstract: A display device includes: a display panel, a pattern layer, and a low refractive layer having a refractive index lower than a refractive index of the pattern layer. The display panel includes: a base layer; a pixel definition layer disposed on the base layer, where a pixel opening is defined in the pixel definition layer; an emission layer disposed in the pixel opening; an anti-reflection layer disposed on the emission layer; and an encapsulation layer disposed on the anti-reflection layer. The pattern layer, the low refractive layer, or the encapsulation layer includes at least one of pigment or dye.
