Abstract: A display device includes a display panel, a first insulating layer on the display panel and having a first refractive index, and a second insulating layer on the first insulating layer and having a second refractive index. The display panel includes a pixel definition layer in which a plurality of emission openings are defined, and a plurality of light emitting elements that respectively correspond to the plurality of emission openings. The first insulating layer has a plurality of openings that correspondingly overlap the plurality of emission openings. Each of the plurality of emission openings extends in an extending direction. Each of the plurality of openings extends in a direction that intersects an extending direction of an overlapped emission opening.
