Abstract

A method for manufacturing a display panel provided in an embodiment according to the present disclosure comprises: forming a light reflecting member on a support member in such a manner that the light reflecting member comprises a plurality of protruding structures which is arranged on the support member in an array form and surfaces of which define an enclosed area; and forming a first electrode and a light guide in order on the support member formed with the light reflecting member, charged particles being provided between the light reflecting member and the first electrode.

Claims (31)

1. A method for manufacturing a display panel, comprising:

forming a light reflecting member on a support member in such a manner that the light reflecting member comprises a plurality of protruding structures which is arranged on the support member in an array form and surfaces of which define an enclosed area; and

forming a first electrode and a light guide in order on the support member formed with the light reflecting member, charged particles being provided between the light reflecting member and the first electrode;

wherein a protruding structure of the plurality of protruding structures located in a spacing area, which is an area where an orthogonal projection of an area between adjacent portions of the first electrode on the support member is located, has a height larger than a height of another protruding structure of the plurality of protruding structures.

2. The method according to claim 1 , wherein the light reflecting member is a second electrode.

3. The method according to claim 1 , wherein the forming the light reflecting member on the support member comprises:

forming a second electrode on the support member; and

forming a reflecting component comprising the plurality of protruding structures on the support member formed with the second electrode.

4. The method according to claim 1 , wherein the surfaces of the plurality of protruding structures are smooth.

5. A display panel comprising:

a support member;

a light reflecting member provided on the support member; and

a first electrode and a light guide arranged in order on the support member provided with the light reflecting member,

wherein charged particles are provided between the light reflecting member and the first electrode;

wherein the light reflecting member comprises a plurality of protruding structures which is arranged on the support member in an array form and surfaces of which define an enclosed area, and wherein a protruding structure of the plurality of protruding structures located in a spacing area, which is an area where an orthogonal projection of an area between adjacent portions of the first electrode on the support member is located, has a height larger than a height of another protruding structure of the plurality of protruding structures.

6. The display panel according to claim 5 , wherein the light reflecting member is a second electrode.

7. The display panel according to claim 5 , wherein the light reflecting member comprises a second electrode and a reflecting component,

the second electrode is provided on the support member, and

the reflecting component is provided on the second electrode and comprises the plurality of protruding structures.

8. The display panel according to claim 7 , wherein the reflecting component is made of a metal oxide.

9. The display panel according to claim 5 , wherein the surfaces of the plurality of protruding structures are smooth.

10. A display device, comprising the display panel according to claim 5 .

11. The display device according to claim 10 , wherein the light reflecting member is a second electrode.

12. The display device according to claim 10 , wherein the light reflecting member comprises a second electrode and a reflecting component,

the second electrode is provided on the support member, and

the reflecting component is provided on the second electrode and comprises the plurality of protruding structures.

13. The display device according to claim 12 , wherein the reflecting component is made of a metal oxide.

14. The display device according to claim 10 , wherein the surfaces of the plurality of protruding structures are smooth.

15. The method according to claim 1 , wherein each of the plurality of protruding structures comprises a triangular prism.

16. The display panel according to claim 5 , wherein each of the plurality of protruding structures comprises a triangular prism.

17. The display device according to claim 10 , wherein each of the plurality of protruding structures comprises a triangular prism.
