Abstract: A display device includes a substrate and a plurality of pixels positioned on the substrate. Each pixel includes a first electrode, a partition wall including a first opening overlapping the first electrode, and a low refractive layer including a second opening overlapping the first opening. The plurality of pixels includes a first plurality of pixels having a first gap between an edge of the first opening and an edge of the second opening and a second plurality of pixels having a second gap between an edge of the first opening and an edge of the second opening. The first gap and the second gap have different lengths from each other. At least one of the first plurality of pixels and at least one of the second plurality of pixels emit light of the same color as each other.
