Title:
METHOD FOR MANUFACTURING LIQUID CRYSTAL PANEL
Document Type and Number:
WIPO Patent Application WO/2010/044218
Kind Code:
A1
Abstract:
Disclosed is a method for manufacturing a liquid crystal panel that can solve problems involved in a conventional polarizing film, that is, a problem (1) that a pressure-sensitive adhesive and a release liner used in the polarizing film are so bulky and heavy that the transport efficiency of the polarizing film is low, a problem (2) that the lead time of the manufacture of the polarizing film is long since the pressure-sensitive adhesive should be cured after lamination onto a polarizing plate, and a problem (3) that the pressure-sensitive adhesive tends to be deteriorated due to the influence of moisture contained in the polarizing plate, and thus, the quality-guaranteed period of the polarizing film cannot be prolonged.
The polarizing film obtained by the method comprises a laminate of a base film and a polarizing thin film and is advantageous in that the dimensional change caused by a change in temperature or humidity is as small as being approximately one-tenth of that of the conventional polarizing film. Therefore, the polarizing film is advantageous in that there is no need to previously laminate the pressure-sensitive adhesive (adhesive processing), the use of the release liner is not also required, the necessity of curing the pressure-sensitive adhesive can be eliminated, and the pressure-sensitive adhesive is not deteriorated.
