Abstract: A display device includes a substrate including a display area and a non-display area surrounding the display area, a light emitting structure disposed on the substrate in the display area, a thin film encapsulation layer disposed on the light emitting structure, an optical structure including a first refractive pattern and a second refractive pattern, and a partition wall disposed on the substrate in the non-display area and surrounding the second refractive pattern. The first refractive pattern is disposed on the thin film encapsulation layer, and overlaps the light emitting structure. The second refractive pattern covers the first refractive pattern, has a refractive index smaller than a refractive index of the first refractive pattern, and includes an organic material.
