Abstract

A motherboard and a manufacturing method thereof, a cover plate and a manufacturing method thereof, and a display device are provided. The manufacturing method of the motherboard includes: forming an ink pattern layer on a base substrate, the ink pattern layer including a plurality of hollow regions; applying a curable liquid onto the base substrate to cover the ink pattern layer; and curing the curable liquid to form a cured layer covering the ink pattern layer.

Claims

1. A display device, comprising:

a display panel;

an adhesive layer provided on the display panel; and

a cover plate to cover the adhesive layer, wherein the cover plate comprises;

a base substrate provided on the adhesive layer, wherein the adhesive layer directly contacts each of the base substrate and the display panel;

an ink pattern provided in an border region of the base substrate, wherein the ink pattern protrudes from the base substrate; and

a cured layer provided on the base substrate to cover the ink pattern, wherein the cured layer comprises a first portion provided directly on the ink pattern and a second portion other than the first portion, a thickness of the first portion is smaller than a thickness of the second portion, and a surface, away from the base substrate, of the first portion is flush with a surface, away from the base substrate, of the second portion;

wherein the base substrate is a flexible base substrate, the flexible base substrate comprising at least one material selected from the group consisting of triacetate cellulose, cycloolefin polymer, and polyimide.

2. The display device according to claim 1, wherein the flexible base substrate is a polarizer.

3. The display device according to claim 1, wherein the base substrate has a thickness in a range of 5˜

500 μ

m.

4. The display device according to claim 1, wherein the ink pattern has a thickness in a range of 5˜

50 μ

m.

5. The display device according to claim 1, wherein the cured layer comprises at least one material selected from the group consisting of polymethyl methacrylate, polyethylene terephthalate, polyurethane, silicone, and organic composite materials.

6. A display device, comprising:

a display panel;

an adhesive layer provided on the display panel; and

a cover plate to cover the adhesive layer, wherein the cover plate comprises;

a base substrate provided on the adhesive layer, wherein the adhesive layer directly contacts each of the base substrate and the display panel;

an ink pattern provided in an border region of the base substrate, wherein the ink pattern protrudes from the base substrate;

a cured layer provided on the base substrate to cover the ink pattern, wherein the cured layer comprises a first portion provided directly on the ink pattern and a second portion other than the first portion, a thickness of the first portion is smaller than a thickness of the second portion, and a surface, away from the base substrate, of the first portion is flush with a surface, away from the base substrate, of the second portion;

an anti-reflection layer, provided on a side of the cured layer away from the base substrate; and

an anti-fingerprint-and-scratch layer, provided on a side of the anti-reflection layer away from the base substrate to sever as an outmost layer of the cover plate;

wherein the base substrate is a flexible base substrate, the flexible base substrate comprising at least one material selected from the group consisting of triacetate cellulose, cycloolefin polymer, and polyimide.

7. The display device according to claim 6, wherein the flexible base substrate is a polarizer.

8. The display device according to claim 6, wherein the base substrate has a thickness in a range of 5˜

500 μ
