Abstract

A method comprising: subjecting at least one or more barrier film components and one or more polariser film components for a liquid crystal display device to a first drying process; thereafter combining at least said barrier film components and polariser components to assemble upper and lower sub-assembly components; subjecting the upper and lower sub-assembly components to a second drying process; and thereafter combining the upper and lower sub-assembly components with at least a liquid crystal cell component to assemble a liquid crystal device.

Claims (13)

1. A method comprising:

subjecting at least one or more barrier film components and one or more polariser film components for a liquid crystal display device to a first drying process;

thereafter combining at least the barrier film components and polariser components to assemble upper and lower sub-assembly components;

subjecting the upper and lower sub-assembly components to a second drying process; and

thereafter combining the upper and lower sub-assembly components with at least a liquid crystal cell component to assemble a liquid crystal device.

2. The method according to claim 1 , wherein the first drying process comprises either (i) baking the barrier film components and polariser components in an atmospheric pressure environment whose water vapour content has been reduced; and/or (ii) keeping the barrier film components and polariser components in a reduced pressure environment.

3. The method according to claim 1 , wherein the second drying process comprises either (i) baking the sub-assembly components in an atmospheric pressure environment whose water vapour content has been reduced; and/or (ii) keeping the sub-assembly components in a reduced pressure environment.

4. The method according to claim 1 , wherein: each of the upper and lower sub-assembly components comprises, between a stretched polymer dichroic film and one or more barrier coatings, at least one polymer film having a higher water vapour transmission rate (WVTR) than both the stretched polymer dichroic film and the one or more barrier coatings.

5. The method according to claim 4 , wherein the at least one high WVTR film comprises one or more of:

a support film supporting the one or more barrier coatings of a barrier film component;

a support film supporting the stretched polymer dichroic film of a polariser component; and

an adhesive film between the barrier film component and the polariser component.

6. The method according to claim 2 , wherein the atmospheric pressure environment whose water vapour content has been reduced has a relative humidity of about 0%.
