Method for manufacturing light-emitting device
View Patent ↗An object of one embodiment of the present invention is to provide a more convenient highly reliable light-emitting device which can be used for a variety of applications. Another object of one embodiment of the present invention is to manufacture, without complicating the process, a highly reliable light-emitting device having a shape suitable for its intended purpose. In a manufacturing process of a light-emitting device, a light-emitting panel is manufactured which is at least partly curved by processing the shape to be molded after the manufacture of an electrode layer and/or an element layer, and a protective film covering a surface of the light-emitting panel which is at least partly curved is formed, so that a light-emitting device using the light-emitting panel has a more useful function and higher reliability.
1. A method for manufacturing a light-emitting device comprising the steps of:
forming a light-emitting panel having a shape of a flat plate;
processing the light-emitting panel having the shape of the flat plate into a shape at least partly curved;
fixing the light-emitting panel having the shape at least partly curved; and
forming a protective film to cover an entire surface of the light-emitting panel having the shape at least partly curved after the fixing of the light-emitting panel into the shape at least partly curved,
wherein the entire surface of the light-emitting panel is covered with only the protective film.
2. The method for manufacturing a light-emitting device according to claim 1 further comprising the steps of:
providing a supporting member in contact with an outer side or an inner side of the light-emitting panel having the shape at least partly curved so as to maintain the shape of the light-emitting panel before forming the protective film.
3. The method for manufacturing a light-emitting device according to claim 1 further comprising the steps of:
providing a supporting member in contact with the protective film to cover an outer side or an inner side of the light-emitting panel having the shape at least partly curved so as to maintain the shape of the light-emitting panel after forming the protective film.
4. The method for manufacturing a light-emitting device according to claim 1 ,
wherein the protective film is formed with a sputtering method.
5. The method for manufacturing a light-emitting device according to claim 1 ,
wherein the protective film comprises silicon nitride.
6. A method for manufacturing a light-emitting device comprising the steps of:
forming a light-emitting panel having a shape of a flat plate, a method for forming the light-emitting panel comprising the steps of:
forming an element layer over a substrate;
transferring the element layer from the substrate to a supporting substrate;
transferring the element layer from the supporting substrate to a first sealing member having a shape of a flat plate;
forming a light-emitting element electrically connected to the element layer; and
forming a second sealing member over the element layer and the light-emitting element;
processing the light-emitting panel having the shape of the flat plate into a shape at least partly curved;
fixing the light-emitting panel having the shape at least partly curved; and
forming a protective film to cover an entire surface of the light-emitting panel having the shape at least partly curved after the fixing of the light-emitting panel into the shape at least partly curved,
wherein the entire surface of the light-emitting panel is covered with only the protective film.
7. The method for manufacturing a light-emitting device according to claim 6 further comprising the steps of:
providing a supporting member in contact with an outer side or an inner side of the light-emitting panel having the shape at least partly curved so as to maintain the shape of the light-emitting panel before forming the protective film.
8. The method for manufacturing a light-emitting device according to claim 6 further comprising the steps of:
providing a supporting member in contact with the protective film to cover an outer side or an inner side of the light-emitting panel having the shape at least partly curved so as to maintain the shape of the light-emitting panel after forming the protective film.
9. The method for manufacturing a light-emitting device according to claim 6 ,
wherein the protective film is formed with a sputtering method.
10. The method for manufacturing a light-emitting device according to claim 6 ,
wherein the protective film comprises silicon nitride.
