Display device and method of manufacturing display device
A display device includes a flexible substrate, a self-luminescent element, and a support member. The flexible substrate has a first face and a second face opposed to the first face. The self-luminescent element is provided on the first face of the flexible substrate. The support member includes a magnetic material and is provided on the second face of the flexible substrate.
1. A method of manufacturing a display device, the method comprising:
attaching a first support member to a second face of a flexible substrate;
forming a self-luminescent element on a first face of the flexible substrate, the first face being opposed to the second face of the flexible substrate to which the first support member is attached;
removing the first support member from the flexible substrate after the forming of the self-luminescent element; and
attaching a second support member to the second face of the flexible substrate after the removing of the first support member, the second support member including a magnetic material.
2. The method according to claim 1 , further comprising:
holding the flexible substrate to which the second support member is attached on a substrate holder configured to generate a magnetic field, the second support member being positioned between the flexible substrate and the substrate holder while the flexible substrate is held on the substrate holder.
3. The method according to claim 1 ,
wherein the first support member to be attached to the second face of the flexible substrate includes glass.
4. The method according to claim 1 ,
wherein the flexible substrate includes polyimide.
5. The method according to claim 1 ,
wherein the magnetic material comprises ferrite-based stainless steel or martensite-based stainless steel.
6. The method according to claim 1 ,
wherein the second support member includes a metal material.
7. The method according to claim 1 ,
wherein the second support member comprises a metal plate.
8. The method according to claim 1 ,
wherein the second support member has a thickness in a range from about 5 micrometers to about 150 micrometers.
9. The method according to claim 1 ,
wherein the attaching the second support member comprises attaching the second support member to the second face of the flexible substrate so as to entirely extend over the second face.
10. The method according to claim 1 ,
wherein the attaching the second support member comprises attaching the second support member at least along an end of the second face of the flexible substrate.
11. The method according to claim 1 ,
wherein the removing the first support member from the flexible substrate comprises performing laser irradiation.
12. The method according to claim 1 ,
wherein the self-luminescent element comprises an organic electroluminescent element.
13. The method according to claim 2 ,
wherein the substrate holder comprises a tray to be carried between processes or a mounting stage, and
a face of the substrate holder on which the second support member is to be fixed is substantially flat.
14. The method according to claim 2 ,
wherein the substrate holder includes stainless steel.
15. The method according to claim 2 , further comprising:
performing an inspection with the flexible substrate being held by the substrate holder, the inspection comprising an inspection of a display state of the self-luminescent element.
