Abstract

A manufacturing method of a liquid crystal display according to an exemplary embodiment of the present invention includes: coating spherical spacers mixed with a first adhesive on a first insulation substrate; coating a second adhesive on the spherical spacers; aligning the second insulation substrate with the first insulation substrate to contact the second adhesive; and hardening the first adhesive and the second adhesive to adhere the spherical spacers to the first insulation substrate and the second insulation substrate.

Claims (14)

1. A method for manufacturing a liquid crystal display comprising:

coating spherical spacers mixed with a first adhesive on a first insulation substrate;

coating a second adhesive on the spherical spacers;

aligning a second insulation substrate with the first insulation substrate to contact the second adhesive; and

hardening the first adhesive and the second adhesive to adhere the spherical spacers to the first insulation substrate and the second insulation substrate, wherein the hardening of the first adhesive and the second adhesive to adhere the spherical spacers to the first insulation substrate and the second insulation substrate includes:

hardening the first and second adhesives through UV irradiation, pressing and attaching the first insulation substrate and the second insulation substrate to each other after softening the first and second adhesive through heat treatment, and

hardening the first and second adhesives through an UV irradiation for a second time.

2. The method of claim 1 , wherein coating the spherical spacers comprises roll printing.

3. The method of claim 2 , wherein the first adhesive and the second adhesive are made of the same material.

4. The method of claim 1 , wherein the first and second adhesives are acryl-based adhesives.

5. The method of claim 1 , wherein the UV irradiation is executed within 30 seconds.

6. The method of claim 1 , wherein the heat treatment is executed in a temperature of 100° C. for 30 minutes.

7. The method of claim 1 , wherein the insulation substrate is a flexible substrate.

8. The method of claim 7 , wherein the flexible substrate is a plastic substrate.
