1. A display device comprising:
a substrate;
a plurality of pixels on the substrate;
a first electrode on the substrate;
a partitioning wall on the first electrode, the partitioning wall comprising a plurality of first openings, wherein a first opening of the plurality of first openings overlaps the first electrode and a pixel of the plurality of pixels;
a touch detection electrode on the partitioning wall;
a low refractive layer on the partitioning wall and the touch detection electrode, the low refractive layer comprising a plurality of second openings, wherein a second opening of the plurality of second openings overlaps the first opening and the pixel; and
a high refractive layer on the low refractive layer,
wherein planar shapes of the first opening and the second opening are polygons comprising a plurality of sides,
wherein, for each of a first color pixel of the plurality of pixels and a second color pixel of the plurality of pixels having a color different than a color of the first color pixel, a first shortest distance between one side of the plurality of sides of the first opening and the second opening is different than a second shortest distance between other side of the plurality of sides of the first opening and the second opening in a plan view, and
wherein the one side and the other side are opposite or adjacent.
