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.
Claims11
A display device comprising:
- a substrate;
- light-emitting elements to emit visible light, arrayed in a regular manner and separated from each other on one surface of the substrate;
- and
- a film member covering each of the light-emitting elements and closely adhering to the one surface of the substrate between the light-emitting elements, the film member being waterproof, having transmissivity to visible light, and having weather resistance, wherein
- each of the light-emitting elements comprises a light emitting diode covered with a resin having a weather resistivity that is lower than a weather resistivity of the film member.
A method for manufacturing a display device, the method comprising:
- arranging light-emitting elements to be arrayed in a regular manner and separated from each other on one surface of a substrate, and mounting the light-emitting elements on the surface of the substrate, the light-emitting elements emitting visible light;
- and
- covering, with a film member, the one surface of the substrate on which the light-emitting elements are mounted, and causing the film member to closely adhere to the one surface of the substrate between the light-emitting elements, the film member being waterproof, having transmissivity to visible light, and having weather resistance, wherein
- the arranging and mounting of the light-emitting elements includes arranging and mounting the light-emitting elements that include light emitting diodes covered with a resin having a lower weather resistivity than the film member.
A method for manufacturing a display device, the method comprising:
- arranging light-emitting elements to be arrayed in a regular manner and separated from each other on one surface of a substrate, and mounting the light-emitting elements on the one surface of the substrate, the light-emitting elements emitting visible light;
- and
- applying a coating material to the one surface of the substrate on which the light-emitting elements are mounted, to coat with the coating material (i) each of the light-emitting elements and (ii) the one surface of the substrate between the light-emitting elements, the coating material being waterproof and having transmissivity to visible light, wherein
- the arranging and mounting of the light-emitting elements includes arranging and mounting the light-emitting elements that include light emitting diodes covered with a resin having a weather resistivity that is lower than a weather resistivity of the coating material.
