Abstract
A display device includes a substrate, light-emitting elements that emit visible light, and a protective film that is waterproof, has transmissivity to visible light, and has weather resistance. The light-emitting elements are arrayed in a regular manner and separated from each other on one surface of the substrate. The protective film covers each of the light-emitting elements and closely adheres to the one surface of the substrate between the light-emitting elements. Each of the light-emitting elements includes light emitting diodes covered with a resin having a weather resistivity that is lower than a weather resistivity of the protective film.
