Abstract: Provided is a display device including first to third pixels and first to fourth cap layers. The first cap layer is located over and overlaps with the first to third light-emitting elements and extends from the first pixel to the third pixel through the second pixel. The second and third cap layers are located over the first cap layer and respectively overlap with the second and third light-emitting elements. The fourth cap layer is located over the first to fourth cap layers. The first to third pixels are arranged in this order. The first to third light-emitting elements are configured so that an emission wavelength of the second light-emitting element is shorter than an emission wavelength of the third light-emitting element and longer than an emission wavelength of the first light-emitting element. A thickness of the third cap layer is larger than a thickness of the second cap layer.
