Abstract: A display device is disclosed that includes an insulating layer located on a substrate. The insulating layer includes a plurality of concave portions which are located in a plurality of subpixels. An area of a first concave portion disposed in a first subpixel among the plurality of subpixels is larger than an area of a second concave portion disposed in a second subpixel among the plurality of subpixels. A plurality of lens parts are located on the insulating layer, and include a first lens part corresponding to the first concave portion and a second lens part corresponding to the second concave portion. It is possible to provide a display device capable of improving light extraction efficiency.
